    I was thinking about relocating my gas tank so that i had better departure angles. Has anyone done this and were did you put it? Would it be safe to put it in the back?
    Thanks!!!

    Stuck? Isn't that a bird!

    You can put a gas tank in the back, but I would use a fuel cell, not the stock tank. Get a fuel cell with the foam in it so if you rollover it wont come out as easy. Also buy the check ball for the vent. The check ball closes wen the tank is upside down. In order to do it in drag racing you are suppose to have some sort of wall in between the tank and you. Kind of like a firewall. Without it you dont pass tech. Also I would no leave the top on because of the fumes.

    then you have to put down the tailgate, to fill up. and how big of a fuel cell can you get? in my opinion the only thing inside that should be explosive is the gas that comes from grandmoms beans. just a thought.

    I'm putting a fuel cell in mine since I bobbed it. It's an RCI 20 gal aluminum fuel cell and runs about $225. No tailgate though. MTPockets has one in his too with the bed bob. You can get 32 Gal poly cells for less than that but they didn't fit my required dimensions.

    You can run a filler tube from the cell to the sidewall of your rig with no problem. The biggest commercially made cell I've ever seen was 32 gallon, but you can get any size you want custom made.

    and on the safety issue....thin wall tank under the truck to get hit and bashed and leaky, or thick wall tank safely inside the truck where it won't get abused...think about that one. Why do pro street race trucks have them in the bed? A leaky tank that explodes will probably get you either way, but as for vulnerability, it sure takes a lot more hits underneath.

    i guess it's a mental thing. would you rather be in a room with a bomb, or in the room next door. either way your phucked. and i didn't know they made fuel cells that big, course, that's what she said ;-]

    They make 40 gallon fuel cells. Look around and you can find them.

    How about just raising it and the floor with it,I don't think anyone has thought of that.Dosent seem like to much fabrication and you would still have the whole floor just not as deep...

    Well, just a question for you guys then. I have not drug my gas tank on any trail that I have been on, not to say that I could not take a bad fall and land on it or something. My questions is this, how many of you have drug your gas tank, and or punched a hole in it. I have a skid on my 31 gallon one in the 77 I drive.

    On Steve Frisbies Blazer the gas tank was raised 2", to match the 2" body lift, by simply cutting the crossmembers and raising them, then welding them back in place. So far he has had no problems dragging his. Mine however runs the same rear lift and 2" body lift, but I have not raised the tank and I have drug it a couple of time and landed on it hard enough once to actually bend the skid plate and smash the bottom of the tank. I will be raising my tank in the future. Just my 2 cents.

    I may be slow, but I sure am fat!

    i've dragged mine back when it was stock, probably wouldn't now that it's lifted, but with the bed bob I didn't have much choice.

    I've drug at the back so many times that I built a metal "cage" around the tank.... and it's probably time for a new one!
    The most logical place for relocation is in the bed, but -nobody should ever be sitting on it.... and I don't think you should ever have a top on it again!

    72 and older trucks ran a tank in the cab. So did old fords. Put it behind the back seat. Problem is I think they are only 12 gallons.

    It's not my damn planet monkey boy!

    yep, and on FJ40 landcruisers, the tank is in the space between the passenger seat and the floor.

    well after going to llano twice, i think i have reduced the space in my tank by about 3 or 4 gallons. I have the stock skid plate on there and it flexes in and then pops back out. It actually looks like there is no damage at all because the skid plate looks normal, but i was wondering how my tank wasn't holding around 31 gallons anymore when i was almost empty. So then i discovered this situation. and yes it wasn't crunched before hand. Thank god it didn't have any holes in it. So when i do my body lift i'm raising it the same amount and making a beefier skid plate for it. Later - Doug
