    Well, here is whats going on. truck has two tanks. wireing is messed up and i cant get anything to work right. So in comes the fuel cell. the biggest i can find so for a a 20gal. from jegs. Would like bigger. I was going to mount it in the bed and put some kind of steel around it to protect it. I think the tbi needs about 10 to 14psi to work. So is this a OK idea or what. im not sure what else to do. i thought this would be cheaper then putting the two tanks back in. So what do you guys think? good way to go?? any ideas would be great

    thanks

    Look for a polyethylene tank instead. They have them, somewhere, in tanks holding up to 50 gallons. (!)

    I know JC Whitney sells them but I'm not a big fan of them. Maybe Google "50 gallon fuel tanks" and see what pops up?

    50 gallon tanks I know are available in Vans I don't think they offer anything that big in single tank for a pickup.
    They do offer bigger saddle tanks to get a total of 50 gal.

    By the way those poly tanks are not cheap.
    Last time I was looking into getting one they were $500 each.

    I'm currently mounting a 16 gallon from summit. Moving the rear crossmemeber forward to mount it nicely. I started it last night and will finish it tonight. I'll try to post some pics. below is a pic of what it looked like before i started. The tank is going to sit between the frame rails and still doesn't hang down as low as a stock blazer tank. Its a trail only rig, so i figure if i need more fuel for a long trip I can always mount another tank on the flat bed and run its output line to the other tank. For 120 bucks with foam in it, its not a bad deal. its another 25 for the mounting straps, but you could make your own cheaper.

    PS- What the hell do you need 50 gallons for anyway? Have you seen gas prices? Thats roughly 400lbs of fuel youre luggin around, and $125 @2.50/gallon to fill your tank. A teenager with a siphon would hit the jackpot finding your rig, lol.

    You could use a blazer or suburban tank. They come in 40 gallon capacity. Still use stock fuel pump and sending unit then. Build a custom mount where the spare tire would go under the bed.

    I cant find my pics but I seen one where the guy took a new tank and welded a inlet tube to the driverside so he could fill from either the laft or right side of the truck. He just ran exhaust tubeing from the fuel door to the back then used rubber hose to the tank. I'll keep looking. Dont know if you have a bodylift but I think this guy had one to make it work.

    Talked to my brother he has them. When he gets home he is going to send them to me. So probably late tonight or tomorrow. Really is a nice setup. I believe he used the blazer tank straps and it just about looked factory.

    I wish we had the pic of the top. He did one heck of a job on the two inlets. My bro is still looking though.

    I was reading RCI information about their cells, and for the poly cells they recommend having full support under the cell, like a floor or bed mounting.
    Also have you considered a foam filled cell.
