I'M BATVAN has never ending wants and needs....
I keep thinking about the motto "Do it nice or do it twice"...well I have done a couple things a couple times now.
One of the things that sometimes bothered me was the cut down fuel tank, at 28 gallons its a bit small for the thirsty V10. Other than being in the "backcountry" a few times where having to head to the gas station before I was done playing, I also dislike being on a road trip and having EVERY stop be at a gas station. Its nice to break away from the logo metropolis and just stop at a restarea or somewhere remote as we usually have everything we need.
This was actually more of an impulse buy than anything. The result of a thread on Sportsmobile forum where a member mentioned that
http://www.aerotanks.com/ shipped their tanks out to customers for DIY. I was under the impression that it was a dealers only install thing.
I called and talked to Jake about their tank, freight cost, etc.
It was a bit over $1200 shipped and took about a month to receive on a pallet at a local terminal.
I had been suspecting my fuel pump was going out (another one of those things that probably should have been done when the tank was modded and 100K miles) so I was expecting to have to drop the tank anyways for a pump replacement so what the hell right?
I purchased a new fuel pump/hanger assembly,

Here are the pics of the tank,
(above) The steel angle at the bottom attaches to the frame rail. The angle at the left and right attach to the body.
I have seen a lot of nice aftermarket tanks that I could call "a work of art" this isn't one of them. But you never see it so who cares right?
Its an aluminized steel tank, its a bit warped, I did get the skid plate option but it came welded to the bottom of the tank. A skid plate to me has separation from the object its protecting, but whatever, this has a "thickened" bottom.
There are two ports on top, for the push in twist vents in the OEM tank, mine had two but they were the same size and these two are different sizes. I don't think I have an "OBDII" connector on my OEM tank.
When talking to Jake on the phone, because I had received the directions for the rear mounted 40 gallon tank (wait they have an aftermarket 40 gallon rear mounted tank?), he told me that the little sheetmetal disc in the hardware pack was for welding over that port if you don't need it. I said, "You want me to weld on the tank?" I ended up using some epoxy on well prepped and cleaned surfaces.
I didn't use the supplied epoxy either.
They supply epoxy and recommend epoxying the fuel pump hanger down (per their instructions). Jake said on the phone he didn't even think you could get the seals anymore. Well my new pump hanger had a new seal, so I didn't epoxy mine down.
Another good reason for epoxying it down is because the top of the pump hanger is now well below the fuel height when full. In fact I drove 4 days this last week before my fuel gauge moved from "E"
Mine hasn't leaked yet.
Installation was straight forward, had to drill some holes above my head with hot metal shavings falling on my arms and face. The filler neck is a little cobbled together and their filler neck doesn't except the backflow prevention valve fitting in the tank correctly. I cobbled it into the reducer and hose/clamps they included but I think I would have preferred to reuse the OEM rubber hose/neck. The filler neck also doesnt allow much body to tank flex, like the OEM neck.
I think my specific installation issues have a lot to do with this tank being universal with many different years/fuels/models, etc.
I have had another (SMB) member inquire about the tank, mentioning that it hangs very low. I agree it hangs much lower, not any lower than the Tcase but it is more in the break over area. I don't push these limits so it being low doesn't bother me.
My biggest complaint is that its attached to the frame and the body, it seems like it would limit the flex between the two, and also put stress on the tank itself.
EDIT: The OEM (and ujoint tank) hang off the frame by cradles/straps which flex and don't transmit such stress to the tank itself.
What do you guys think?
