Custom 35 gallon gas tank for '09 Tacoma

I hate to be a kill joy here and unlike others who have posted on this topic, I don't claim to be an expert on gas tank manufacturing. But I do know quite a bit about vehicle liability and the insurance industry. Those of you that have this tank already installed and those contemplating a purchase of one -- have you really considered the liability you have incurred? Here we have a product produced by a company with no expertise in the field that has never been tested in any way. It is now public knowledge that one of the tanks has failed -- there is no reason to assume the rest of the tanks don't have the same defect. If the tank rusts through and fuel drips on a hot exhaust system, the results would be catastrophic. The fact that the company made the tank out of material that is subject to corrosion, given all the materials available today, should be a wake up call. In the real world, every tank would be recalled and inspected.

I can guarantee that no automotive insurance company on the planet would insure a vehicle if it knew about this modification, especially now with the failure being public. Your state has the right to revoke a vehicle's title if it deems the vehicle to be unsafe and operating on public roads. Go ahead and have the discussion with your insurance company (not your agent) and see what the response is.

We all assume some risk with modifications we make, no question. Even buying and installing a tank from a reputable manufacturer is not without some risk. But in almost 20 years of working with liability and the auto insurance business, this is one of the best examples I have seen of people getting behind an idea without seeing the costs. As Colin Powell famously said: "Experts often possess more data than judgement".

All good information yes but not for nothing but this is kind of product testing thing at this point. I am sure Shane probably contacted whomever involved and actions have been taken. All fabricated goods installed on all our expo vehicles did start somewhere whether the plans went into the dumpster and failed or ended up either DOT approved or offroad only approved. So should everyone close up their fab shops because the insurance company has spoken?

I don't think anybody here claimed to be an expert in gas tanks. Also on the many many 4x4s I've worked on with old gas tanks (pre 90's). Almost all of them had some serious amount of rust inside the tank. Its a really common thing because as Scott mentioned before water in your gas tank wasn't such a big deal up until ethanol hit the market. The only reason they go more unaffected is because they sit higher in the tank and are less finiky due to them being an older system. The other thing to keep in mind is that gas tanks with un-pressurized liquid gasoline don't blow up. Ever. Would you get a fire if you're gas tank leaked out onto your exhaust? Maybe. Another thing to keep in mind is that they place all of the exhaust components on the other side of the truck so once again the fuel coming out of an un-pressurized tank wouldn't be a safety issue in that sense. Also if you read here http://www.fmcsa.dot.gov/rules-regulations/administration/fmcsr/fmcsrruletext.aspx?reg=393.67 there isnt much in there that isn't covered in this tank because it retains ALL of the factory equipment meaning that it still conforms to DOT rules. Nowhere is corrosion resistance a thought because almost all steel tanks will corrode with time.

Now I do agree that the tanks should have either been made out of something with better corrosion resistance or hot coated with something to begin with. For such a high ticket item its a pretty big oversite but the manufacture is working on it.

Scott, the TRD blower kits are notorious for running a little lean, yielding high exhaust gas temperatures. I'm hoping Toyota installed more than just the blower because if your running stock injectors (especially after the potential rust) I would run an pyrometer to monitor this. I ran an autometer one on my last truck and it helped a lot with keeping the engine happy. AFR/boost gauge is also a good idea. Also I talked with my buddy who is quite the hotrod builder about this product here http://www.por15.com/FUEL-TANK-REPAIR-KIT/productinfo/FTRK/ . Apparently it works like a charm. Even removes all the old rust gunk. I have experience with other POR-15 products and I couldn't be any happier. If your interested let me know, you will probably need more than one kit but I can get you some pretty good pricing on it.

Pyrometer is a great idea but prob go one step further for the amount of money you just dumped into your rig and go with a wideband set up.

Of course not. But IMHO, it hardly seems prudent to risk everything you have worked for to get extra range from a vehicle. And make no mistake -- a good attorney would have a field day with this case in the event of injury or death. We live in a litigous society -- thats the reality. Its always a risk vs reward equation.

And I have seen nothing posted that would indicate that Shane contacted anyone. I think the fact that 9 have been produced and installed is way past the product testing stage.

Original tank update and other misc. ramblings

Hey Gents, I have been following this thread with great interest. Not only did I build the first tank (or, more correctly, deployed Shane on the project) I live in Bend and have had numerous projects, big and small, done by Shane and his crew.

To start, I want to express how impressed I am with your approach to the issues you have encountered, Scot. Clearly you were dealing with a major bummer (with associated major bummer costs) and your rational and thoughtful approach and willingness to share what you have learned are in the best traditions of this portal. Well done and thank you.

There is a ton of great information and points of view that have been expressed. I guess the one that most reflects how I feel about this process is that everyone who bought one of these tanks was part of an ongoing R&D process. I may have built the first one, but anyone who has done a modification this significant and this unproven knows (or should know) that it will be a learning experience. I feel for Scot as he learned, the hard way, about what appears to be a rust issue (will be interesting to hear the verdict on the fuel pump once Shane does the mechanical autopsy). Pictures don’t lie and clearly there was rust. There have been a number of hiccups, although none this significant, which through trial and error have been addressed. You nailed it again, Scot: this is a process of innovation. I have confidence that Shane is going to address this issue. In my conversations with him he is already exploring possibilities for a fix. I intend to do a pre-emptive fix as soon as he has this figured out (for what it is worth, early during the build of my tank, it was pointed out by one Portal member that an internal coating might eventually be required to prevent rust---guess we shoulda’ listened).

I have also been interested, and at times amused, by the discussion of potential liability. It is hard to know whether any of the experts in this discussion are lawyers, but I am. Simply having a custom tank that is not certified does not, itself, create liability if there is a problem. At the same time, you probably could NOT put this tank into mass production and sell it, particularly in Calif. without getting the necessary certifications and licenses. Producing a one-off, for off road only tank is another thing altogether, however. The question for all of us that purchased tanks is whether we used reasonable care in the tanks construction, maintenance and use. I have checked off the construction box. Ditto use. And I am now going to address the rust issue. I feel that I have used all available information to make this tank as safe as a gasoline carrying metal box can be. And frankly, this seems a lot safer than having 5 or 10 gallons hanging off on back of my rig in harms way and vulnerable in any sort of rear end collision. Anyway, I appreciate the concern and warnings, but legally I think they are overstated.

As an aside, my insurance company knows about the tank and insures my car—and the tank. In fact, I had a recent run-in with a deer (on coming car going 50mph launched it through my front windshield when I was going 50 for a net 100mph collision. Biggest remaining part of deer was football size. Pieces traveled through the windshield, through the rear seat, through the body of the truck, through the cap roof and into the bed. Bones were stuck in most surfaces of the interior. Piece of something hit me in the face which is a another story altogether). The insurance company wanted to total the truck, but when they saw the cost of replacing all I had put on it, including the tank, they repaired it—better than new. No issues whatsoever with the tank. Moreover they added it to the list of now-insured aftermarket parts (front/ rear bumpers, suspension, winch, bed cap, etc) and my insurance, post accident, increased $25 per year.

Finally, I have not had any problems with the tank, aka Super-Tanker. Early on there were some warning light issues that Shane addressed and fixed. I was recently in Shane’s shop getting 4:54 gears put in and he did an inspection of the tank. After thousands of hard off road miles, no issues. No movement of the tank, nothing loose, no chafing, no problems at all. We did not inspect the inside for rust---waiting to see what Scot’s fuel pump shows, but that is probably next.

The tank has been one of the best modifications I have added. If your truck is a daily driver, don’t bother. But if you do serious off road travel increased range is a big deal, at least to me. In the end the process of whether to modify our rigs, and to what extent, is a personal choice. As someone noted, they all involve risk. Personally I haven’t found a risk-free way to travel off road, but again, like mods, we all make personal choices about risk. I would do this mod again in a heartbeat.

Finally, and many have also pointed this out, none of us could do any better than to have a project like this done by Shane. He is a pro. He is a perfectionist. And he stands behind his work. There are a ton of reasons not to add a tank like this. If, like me, you think the benefits outweigh the risks, see Shane.

well said, I am interested in what your tank looks like though being it is the first and longest one out there, regardless of what the verdict is of the old fuel pump

I was the contributor who mentioned the tank seen in Namibia. Unlike the tank manufactured in Bend, it was all stainless steel. And I know of two Tacomas in the states that Hilux tanks were installed in with minor modifications. So far (2 years) no rust and no issues. Of course, having helped install one (me) is very different than pontificating about a topic he knows nothing about (TangoBlue).

TscotR214,you are a very understanding consumer; not everyone has your perspective and patience for a custom modification of this sort. I hope your vendor appreciates the partner he has in a customer who has proven so willing to assist in developing a superior product. Your reports have made us all a little bit smarter on the quest for extended travel range. Both you and cwvandy have shown an amazing level of integrity and optimism for the capacity of your trucks platform.

I sincerely apologize in advance for polluting your thread but indulge me this instance, please.

kmacafee...

Yes Kevin, you were the contributor who saw some tanks for sale in Namibia, priced within their local economy at $500USD, installed. You also know of two individuals who have installed HILUX LR tanks on their Tacoma's, one of which you helped install, and assert that it was easy. I believe you.

Since then you have continuously sniped at me and two other forum members who have called you out on your empty assertions. I believe you when you say you went to Namibia - I bet you even saw the tank installed - I might have done the same if I traveled to Africa and bought an adventure driving vacation. But just as you spoiled a previous thread on organizing a group buy of this product earlier, my beef with you is that these statements don't assist the OP and his predicament. What was the manufacturer of the tank and the importer that you observed in Namibia? You have never provided that information but insinuated in your comments that the folks sourcing this tank produced in Oregon were knuckleheads for spending their money when all they had to do was import this tank you saw readily available on the African continent (which is not DOT approved). Oh, and that they are dangerously irresponsible knuckleheads no less for purchasing a non-DOT approved tank.

I believe that you are telling the truth when you say that you have two friends and that they own Tacoma's who've installed this imported HILUX tank; but what have you done to elucidate us on that subject? Nothing. No pictures, no statements from them, no write-ups on their experience or modifications required to adapt them from the HILUX to the Tacoma platform, or even where they sourced the tanks from. Perhaps you noted through your rage at my post that I provided the US importer and their contact information. I believe I also mentioned that the container arrived in early April with some auxiliary and long range tanks from Long Ranger, the Aussie company that produces aftermarket aluminized steel tanks, in the event the OP wanted to investigate that option.

Granted I don't have your experience on the subject, you having seen one installed in Namibia and a couple of US friends that put them in, one of which you helped with. I only work at an off-road fabrication shop that restores Land Cruisers, builds expedition vehicles, desert race trucks, rock crawlers, and a few specialized US and overseas government projects. Some of these have auxiliary and LR tanks (that I've helped with). Well then, there's also my Tacoma with it's auxiliary fuel tank and its total 37 gallon capacity; but what would I know.



I didn't mean to steal your thunder Kevin and "pontificate about a subject he knows nothing about."

Please go on Mr. Macafee, based on your 20 year experience in the insurance industry (what did you do in that line of work) or as a bicycle shop owner, please continue to grace us with your wisdom.

Also, avoid sending me agitated PMs like you did to another member who challenged your expertise on this forum.

Mods on our rigs are always learning experiences, someone has to take the first step in the development process for anything to happen. Guys like TscotR214 who make the initial plunge are the reason we have such good sources of information down the road. Thanks for taking the time to document all of this for future people who might be considering the same thing down the road.

Agreed, basically what I said, time to close up the fab shops guys! haha

After the rust issues a guy might be better off buying a CBI bumper with dual swing outs for a tire and 2 scepter gas cans. Bud built made a container that goes where the spare used to go that holds rotopax fuel containers and this way you can still carry 35 gallons of gas and utilize the stock tank. I know it may not be as cool or as convenient but it'l damn sure work
http://www.toyota-4runner.org/5th-g...ave-re-located-their-spare-tire-budbuilt.html

Looks like it holds 3 4 gallon rotopax containers. 12 gallons there and a 21 gallon tank and you're close to what the aftermarket tank will give you distance wise

cwvandy - I like your thoughts on parts liability, and the tank of course. My insurance company had no problems with me having a custom fuel tank they just were not easily able to insure it. Since my taco is a commercial vehicle and I have an inland marine policy for my field equipment, we are just going to insure it as a permanently mounted piece of field equipment. State laws and insurance companies may have differences. Check your policies. (we had a huge fight over replacing the destroyed tank)

As owner of tank #10 (who then lost it 2 months after Shane installed it) I will be adding one of these again. The highway speed head on collision and roll did not rupture the tank or pull anything from the fuel system loose. Once we have the coated/uncoated/material issues a little more worked out I will give CES my business again. Gas can can be a lifesaver and having the 30-40 gallons of fuel in a stock location frees up the hassle of having to store fuel cans and keep fuel away from water or soil samples.

If you have bumpers than the Budbuilt gas can storage idea or an auxiliary tank looks awesome, for those of us that use the spare tire well and don't have bumpers than the supertanker works great.

For me the huge cost factor of going to Bend from Albuquerque has been taken out of the equation now that CES will ship the tanks. As we all contribute to this mod it gets easier and cheaper for everyone who comes along afterwards.

Kudos to cwvandy and to TscotR214 for sharing their fortunes and misfortunes with this mod. I hope that this rust problem gets figured out ASAP.

What is the cost of the "supertanker" compared to the CBI bumper.

Never mind, found this...

My experience with CES is $1,800 for a tank with powder coating plus a 3-4 day installation charge with whatever accessories are needed (aprox $700-1,000 more). The installation might seem expensive but it it is how CES makes sure that everything works.

CBI bumper with dual swing outs and powder coat is under $1600 and that plate for holding three 4 gallon RotoPax containers from Bud Built can't be that expensive.

I love the idea behind the 35 gallon tank but I think there are other options that give you more bang for your buck and that allow you to carry the came capacity of gas for your truck. Just another option if a guy wants to keep the stock tank.

Can't put a price on piece of mind. There are ranches I lease in Mexico where I'm 4-5 hours to the nearest city and that's a small city and if I break down out there I'm screwed. Given whats happened so far I can utilize Toyota technology and parts and still have the same range. It's a no brainer for me but some folks might like the cool factor of a bigger tank. Whatever works for each individual I guess.

huntsonora - That's the old price and it was more like 3k out the door, plus you have to be in Bend OR for the instal. CES now has a shippable option that greatly reduces the cost. (Aprox 2,500 plus shipping on a pallet). The hardware is still expensive and yes it's bling, but 42 gallons is hard to wrap your brain around until you see it in your gas gauge. Your gas gauge doubles almost perfectly to a 500-600 mile range.

If the Long Ranger tank becomes popular I can see a lot of folks on here going that route. 30 gallons and apox 1300 price tag (wild *** guess) would be a great bang for the buck option, once someone starts shipping them into the states by the container load instead of custom DSL/Fedex pieces.

Ideally I will have a big tank and one of the 2-3 gallon rotopax cans.

Update on post-mortem of my fuel pump in CES tank: kind of a no-brainer given the internal inspection and my posted photos, but issue was indeed confirmed by Shane to be simple rust. Pump itself is fine, but filter is completely stuffed with rust. Allowed truck to start and idle, but any demand beyond idle simply couldn't get enough fuel flow to keep the engine running, typical clogged fuel filter most familiar to anyone spending time in Baja. Thinking back, the CES tank worked flawlessly for months and months, and just happened to take a dump on me in the middle of the desert a full day's drive from home, bad luck on my part. Probably due to my more extreme high-speed desert driving, me giving the inside of the fuel tank a most thorough sloshing, loosening any and all rust straight into the fuel pump filter. Bad design on Toyota's part, having that internal fuel filter beyond visual inspection or trail-side change out. Will probably highly consider internal fuel pump with external fuel filter modification with next tank swap. Even if fuel pump chews rust and dies, at least evidence is visible in external fuel filter and known parts can be brought in for trail-side mechanicals, be it rust, dead flies, sand, water, or whatever sneaks inside our tanks.

Update on the CES Supertankers, Shane now reports all new units get an internal coating to prevent this rust issue. Live and learn. California will probably be the only state with an issue, given our watery fuels, but good to know for any future CES customers, a great CES Supertanker product is now New and Improved, now with burly powder coat outside, epoxy sealing inside. Shane is also making a stainless version, which should be ready for me in a month or two, figured I might as well stay on the guinea pig train and try it out. Mine will have a bottom drain access plug so I can on occasion drain the tank slightly, looking for rust, water, popcorn, etc. as the tank goes through trials. With the internal coating version, I really don't see much more of an issue with this design for those who like the idea of 42 on-board gallons slung down low. I personally don't trust coatings, so I'm opting to try a stainless prototype for myself, but several local fuel distributor folks I've spoken to all report that various commonly applied epoxy coatings should last the life of the tank with no issues.

Side note: Shane is most definitely standing behind his product, and I continue to have confidence and patience in getting this design worked out.

Thanks for the update and the good news. Kudos to the fabricator. It's great to see American craftsmanship and innovation in action.
