aftermarket fuel tanks

[crustyman]

Has anyone installed a aftermarket fuel cell that fits under the body?
What type did u use where did u get from?
How difficult was it to install?
I have found some 20 gal from sumit racing that i think might work.
My goal is to get rid of the stock tank.




Thanks Crustyman

SOR offers an Auxilary 22 Gal fuel tank that could very easily be used as the primary tank. Just go to there site and type in fuel tank. Easy to install.

The tanks at SOR are very pricey. The one at summit are less than $300

I'm in the market for a new fuel tank as well. I'm gonna give cruiserparts.net a call on Monday. They have new OEM style tanks for under $300 on their website. I have had good experiences with their products in the past.

For stk replacement, get a hold of cruiserdan.

Why

 

[crustyman]

I dont like the smell, it takes up space and i think it would be safer under the cab

Thanks all for your intrest and your opinions. good or bad(my ideal of bad) they are all welcome.

im interested in what people have used for tanks under the 40 also, I want to do away with ours from under the seat also.

Fuel tank or fuel cell? Very different. Tanks are DOT approved, generally. JAZ fuel cells are good, as are Fuel Safe.

Unless you want to do a ton of fabrication to make a fuel cell work, buy one of the tanks from MAF, Mark's, Downey, etc that goes behind the rear axle. If you have flipped your springs then you will be stuck like me and have to fabricate something.

Trust me, I would be very happy to spend the $$$ on the turnkey tank solution after spending hours making cardboard prototypes and trying to get them to fit under there and get anywhere near 20 gal. Unless you cut your rear floor you are not going to make any off the shelf fuel cell from Summit work easy back there.

just my opinion here.....

if you have a gas smell, you have a leak or something is not hooked up properly. should be fairly easy to find and eliminate.

I don't know what space you'll gain, the seat is still there, maybe alittle storage under it?

safety? There are hundreds of thousands of these around the world built this way and still on the road. I think it is more protected in the cab surrounded by the body.

I think those cheap Jazz fuel cells are poly and should not go exposed under the truck. I mounted a 22 gallon poly one in the back seat of a VW Baja prerunner I built. A proper Fuelsafe is quite pricey.

Con Fer made a long range tank for your FJ40.

I have one of those 20+ gal auxiliary tanks (came with FJ when I bought it). Check out my resto thread link below and look for posts # 18, 19 and 38. The 38 one shows you the hole that needs to be cut on the quarter panel sheetmetal.

X2 Whenever I've smelled gas in the cab of the 3 FJ40s I've owned, it was a leak in the bottom of the tank.

and i think it would be safer under the cab

Please elaborate on how you came to this conclusion.


Thank you.

if there was any kind of rupture of the tank in a accident I would personally want it outside the vehicle. Occasionally i get the fumes inside the cab and that cant be safe especially for my 8 and 6 yr old kids.

If you get gas smells inside you have problem, why not correct the problem rather than re-design the system?

Safer for your kids is a Volvo. If you get fumes in the cab, you need to repair your vehicle no matter where the tank is. The tank is less likely to get ruptured when it's inside the body in an accident. An accident bad enough to rupture the tank is probably bad enough to ignite the fuel and make the cab into an easy-bake oven anyway. If you've got two kids you're implying that at least one of them is in a lap belt in a side-facing jump seat. That's more not-very-safe than the in-cab fuel tank.

Moral: Don't plan to crash. If you do, don't drive an old vehicle with no safety features.

I don't load my kids up and go on long freeway trips in the '40, but I'm not paranoid about driving them around town in it. My tank is in the cab and I never get fumes (anymore).

I'd have to agree. The tank is probably safer in the stock under seat location beneath the passengers seat than a flimsy tank mount at the rear of the truck or strapped underneath somewhere. I think is especially true if you have beefy rock sliders and a cage to further protect the stock underseat tank.

The fumes are from leaks or bad components, fix them.

A rear mounted fuel cell tank with a skid plate is probably safe but no doubt the 79 and newer tank is the safest. But like I said, I'd run the stock pre-79 tank vs. a cheap tank in the back any day. Problem is, it gets in the way if you try to run a longer drivetrain with the rear spring flipped and the 79 and newer tank gets in the way with a long drivetrain. I think that is why lots of guys still run the tank under the passenger seat or like John Smith go to a tank mounted inside the truck, over the rear axle.

Think Pinto I.E. rear end collision.

What say you guys?
