what not to do with fuel cell - The 1947 - Present Chevrolet & GMC Truck Message Board Network

frost89434 · 05-28-2003, 07:40 PM

Well If you have a fuel cell in your truck and don't have a bed on it . Take my advise and don't let it sit in direct sunlight. I did this with mine and when I came back out it was warped really bad. Just thought I'd give everyone a heads up. JIM

chevykid1969 · 05-28-2003, 08:14 PM

hey man sorry to here about that. can it still be used. I have had mine in for about two weeks and no problems....yet.

Thanks for the heads up.

FRENCHBLUE72 · 05-28-2003, 08:24 PM

I also had the same thing happen when I had a fuel cell located in the bed.

Most of those are made from HDPE (high density polyethylene). This material loses about 50% of its strength once the temperature reaches 150 degrees F. Black HDPE in direct sunlight will reach this temp quickly and then it will sag if empty or there is a slight vac on it from an unvented cap. You can get it back into shape by applying a very light pressure to the tank (3 - 5 psi) and using a heat gun on the areas you want to reshape. BE VERY CAREFUL WITH GAS FUMES AND HEAT!!!!!!!

(progress) thanks for the info. I'll give it a try.

I have mine in the Bed also
It likes to change shapes alright
Always seems to go back to shape though!
Need to cover it with a bed cover!!

VTKidder · 06-03-2003, 09:58 AM

I take it most everyone uses the polyethelene cells when relocating? Any reasoning behind going with them versus Aluminum? Just curious. Woud like to do the same thing eventually ($$!) and just wondering what the advantages are. Thanks.

71GMC_3/4T · 06-03-2003, 10:04 AM

Polyethylene is cheap to manufacture.

I wouldn't use the heat gun trick myself. Call me chicken.
I would leave it in the sun, then add pressure until it was straight, then cool it off quick with cold water.

cruzn72 · 06-03-2003, 07:36 PM

VT I used the RCI tank from Summit and love it. It is aluminum. I agree with 71GMC_3/4T the price is the main issue.

Low69CST · 06-03-2003, 09:06 PM

this post is really making me think about getting an aluminum tank.....

**PICKMUP** · 06-03-2003, 10:44 PM

These don't go anywhere...put them up under the frame and keep the bed clean...no straps either!

VTKidder · 06-04-2003, 07:00 AM

A swap will happen eventually I'm sure. Got other priorities though. I like the ideal of aluminum for some reason. I really can't come up with a reason why, but it just seems like it would be easier to have something that will not expand and contract like plastic. This past year, we had a solid 5 days where it never got above -25F, and another solid week of 100F...a real big change in temps for the year. Who knows...the only reason I want the fuel cell in the rear is safety. God forbid I get T-boned well, the last thing I want is that tank behind me touching off, or breaking open. Being a safety issue, I have no problem forking out the extra cash. There's definitely gotta be a lot of benefits to the plastic though because a LOT of people use them. Thanks for the .02 guys....

landon4421 · 06-04-2003, 10:49 AM

I have a Polyethylene tank, mabe I will have to look into an aluminum tank.

Frank price check please for the tank

Baradium · 06-04-2003, 11:30 AM

I'd like to get an aux tank and keep the original, put a selector switch in... would be really nice for those long trips....

Speaking of tanks....

International had this thing about options. If you wanted it, you could pretty much get it (it used to be that if you wanted something not on the list, they'd add it and keep it on the list, that's how they ended up with over 500 models of pickup trucks).

Anyways, the travelall (think suburban) came with one tank, and you could order an aux tank. And then if you really wanted you could order another aux tank. And another aux tank. And another aux tank.

This gave you one tank between the frame rails in the back that filled from the back (I hear they actually filled from the cargo area), one saddle tank in the rear driver's side. One saddle tank on the front driver's side. One saddle tank on the front passenger side, and one saddle tank on the rear passenger side. This gave you over 100 gallons of fuel capacity... and a whole lot of gas outside your frame rails.

I think I'd want to have a diesel engine if I was going to carry that much fuel (a lot less tendency to go boom). In fact, I'd like to find a rig with that set up, drop a 7.3L diesel in (pretty much a bolt in), and put some reinforcing plates around the gas tanks. Being able to drive across the country on one fill up would be cool!

Just a little fyi for those of you who might contemplate caring.

I missed by about a day an IH diesel traveler. Had two aux tanks for 50 gallons fuel capacity. The TD gives at least 20mpg with 30mpg obtained by many. It was in GA so I had to wait until I could make it down there again before I could look at it, watched the ad and talked to the seller for about a month and someone came down and bought it the day before I was scheduled to look at it.

That fuel range would have been very nice, not to mention the fuel milage.

I've figured out that if I bought a Diesel scout I'd save enough on gas alone to more than cover the insurance and registration, so within a few years it would pay for itself.
