    Has anyone out there made their own gas tank? Details, pics?

    I have been thinking about it. Would 3/16th" be thick enough? There would be a seperate skid plate made if I went through with this.

    And last but not least, what's the formula for figuring volume?

    So it would be something like 13,000" volume? How would I convert that into gallons?

    well [naughty word] now you want me to get technical? why not just measure a stock k5 tank, find the " of volume and make a formula to convert? that is if you know the amt of gallons a stock tank holds, then just use xxxx" of volume=xx gallons, so therefore 13000" of volume =xx gallons, just divide the stock volume by gallons the stock tank holds and there's what you multiply the 13,000 by heh

    I'm having the same debate with myself right now! /forums/images/graemlins/grin.gif Except, I have a custom chassis I built but it's similar in profile to the stock one. What I don't like is the way the stock tank hangs down below the frame rails, waiting to get beaten. I'd like to make one that's shallower and longer/wider. Shouldn't be hard to make a tank once I figure out a good baffle system for the TBI. Only other thing to figure then is how to shorten the stock pump lines to have a shallower tank.
    BTW; I think 3/16 would be plenty strong. In fact; 1/8" sould be overkill if you plated the bottom with a good skid plate.

    Good luck & keep us up to date if you build something.

    Unfortunately, I'm all about seeing how far I can get on a tank of gas, so once everything settles, I'll start taking measurements. Another ten gallons would be nice, and of course that would be a gas tank that hangs down lower, but with the appropriate overkilling skidplate/thickness, I wouldn't have to worry, besides I stay out of rocks anyway.

    I'll sit down and figure out a $$$$ for what I want and that will determine if I get to do this or not........

    I have been thinking about this for a while...
    I want a larger tank but don't want it to hang down as far as the stock 21gal tank.

    What I am thinking about doing is moving the rear crossmember back some to make the tank longer, kicking it out under the frame, and going forward above the axle (with a 4" lift you should have 4" to spare below the floor. I think I could get a 35-40gal tank in there but it would be alot more work than just making it a cube.

    I dont think 3/16 will be thick enough. Maybe you should try 3/8 or 1/2" plate. you know it is gas in there and the stock ones just aren't beefy enough! /forums/images/graemlins/rotfl.gif /forums/images/graemlins/rotfl.gif /forums/images/graemlins/rotfl.gif

    Seriously though, 1/8" is plenty, be sure to baffle the tank properly, and pressure test all welds for leaks. Have fun /forums/images/graemlins/grin.gif
