Larger tank for the XJ?

[The Adam Blaster]

I'm curious if anyone has found and mounted a larger gas tank to their XJ?

I did a google search last week and didn't come up with a whole lot of anything...
I did find an Aussie company that makes a 125 litre tank, and emailed them.
They got back to me adn said the tank should keep the stock ground clearance and departure angles, but would cost $700AUD and the shipping would likely be close to the same. So, $1400 AUD, about $1200USD and just a bit more Canadian $$$.
I personally have a long list of things I could buy with that much money that would be ahead of the larger gas tank.
But I wouldn't mind keeping an eye open for a less expensive option.
I'm not sure if it would be worth while discussing the possibilites of a group buy or not - I would imagine to drop the costs on each unit significantly, you'd likely have to fill a sea can...

interesting.

I wonder if Genright would consider building one , or if one of their existing designs would work on the XJ, since they design them to work on a wrangler with similar rear axles, and frame dimensions...

Their tanks are still about a grand, though.

Have you heard of the breather tube mod? supposedly adds quite a bit of capacity.

the best thing you can do is go hit the junkyard. take a tape measure and see what will fit. i found a 42 gallon suburban gas tank for my wagoneer. it doubled the volume i can carry, and i threw away the old rusty tank.

The problem with newer XJ's is OBD II compliance. There was a company at one time who made bigger tanks for the older XJ's but I don't know of anyone making them for the newer Jeeps. I wish they did.

An Aussie has a write up on his site about it..adds several gallons I think. his site is called go-jeep .com? .org? can't remember but he has tons of write ups w/ great mods.:coffeedrink:

Getlost - I'd be looking for a much more bolt on solution. lol

I hadn't heard of the breather mod, I'll have to look that up.

I just found it, looking for the mod in question as I type this.

 

[getlost4x4]

mine is completely bolt on. drilled 4 holes and used the tank straps to hold it in.

the most expensive part of the system is the fuel filler hose. around here it costs $1.60 per INCH! :Wow1::Wow1::Wow1:

you have to use the right hose or the fuel will eat the rubber.

Good site to bookmark for XJ owners.

He has a spot where he fits an aftermarket tank on, it is actually made by the same company I emailed...

That breather mod is pretty cool!
Talk about cheap as well, I'm going to try and do that sometime this summer.

EDIT: I just caught the note at the very top of the page "This is for metal tanks only and not the plastic ones fitted from 97 on."

I have a '98. Boo-urns...

Aero used to make tanks for the earlier XJ's, dont know if they are still in business.

Guy on another board was at a upull recently, found an aftermarket 30+ tank.. for around $30.. :summinabeach: It was manufactured by an outfit in Chicago. I'll dig out the thread and post the source.

Saw one on Craigslist last year in Phoenix for $200 but I had just recently purchased and installed a gas tank skid plate.

That would be cool!

I have only recently been dail-driving my XJ, and I just replaced both O2 sensors, so I don't have much of an idea what sort of range I currently have.

Here's the stats:

1998 XJ
4.5 Rubicon Express lift
AW$ auto tranny
30 front, 8.25 rear
Stock gears - 3.55
33-12.5R15 Hankook M/T's - the old style (RT01)

I'm very likely to fit 4.56 gears in the future, but it's a big expense to have a shop do it, so at the earliest it will be late in the summer.
I also want/need a front and rear bumper and some sliders, liking JC Offroad for the style/design, but shipping won't work for me. For the rear bumper I want a spare tire mount, as well as a jerry can mount. I might try and get a friend to help me fab up a tire and jerry mount that fits into the trailer receiver for this year so I don't have to store the spare inside the passenger compartment.

I know adding all that weight, and then putting my gear inside the Jeep is going to affect the mileage a bit, but when I had 31's on it, I could squeze about 500 km out of a tank. It would be nice to be able to keep close to that range, but I'm not sure how feasible that is...

I get about 280-310 miles per 16 gallons or so in my 20 gallon tank. Calculates out to around 17-19mpg's. (my tank won't let me fill past 16 gallons. common XJ issue, i guess)

When I first got my Cherokee I was able to put like 18 gallons in, with no issue. Thats how I know i have the larger 20 gallon tank.

thats mostly highway miles.
