Work has been a killer the past couple weeks, but I got out tonight for a while and got the gas tank mounted and most of the fuel line clamped down. As a reminder, this is a tank from a 75 blazer. I used a couple strips of galvanized sheetmetal for the straps. I folded over each end for added strength.
The fuel line is 3/8" aluminum tubing from Summit. It's cheap and real easy to work with. Corrosion shouldn't be an issue. I still need about 3 or 4 tubing clamps and then it's just hooking it up with a couple pieces of rubber hose.
