Hey Guys... Just had a thought...I want a fuel cell, but like evrything else on my truck, I want to make it. I'm a good welder and have access to MIG/TIg and a plasma cutter as well as a whole host of other good metal work/fabrication tool. Anyway, was thinking of useing 12 gauge to 1/8 inch steel (mild). Anybody see any problems with this? I thought of the rust factor, but I think it will be ok. Shouldn't rust bad if I use an additive every other tank or so. I think. Any opinions? I would definatly leak test it and put a roll over vent in it, but any suggestions welcome, ok? Thanks guys, cS Oh yea...Any ideas on a fuel gauge sending unit? How bout safty measures?
