Thread: One way to build a gas tank

Tweet

I'm working on my roadster, it was time to make the gas tank so I thought I would share how I do it.
First I figure out where I want it, on this car I want it in the rear under the rolled pan. I'm using the LS7 427 cu. in. motor. I'm getting a little over 30 mpg out of the engine I have been testing. So, knowing I'm going to use this car to drive long distances I want the tank as large as possible.
I made a tank out of Styrofoam and cut and fit to fill every nook and cranny that I could.
Than I took that to work and had a guy make a drawing of it. Took the drawing to a company that does Lazar cutting and had them cut it out of 1/8 inch 6061 aluminum and then welded it up.
and there ya go a 14 gallon gas tank.
cost $80.00.
I have had custom tanks made for me before, they charged $600 to $800.
