I could probably get some aluminum cut up and have it welded.....baffles would be good and I could put the fittings where I want them.
I'll price materials and a sending unit.
How thick would you recommend ?
.090 or so should be O.K. I think.
Did you set yours in the diamond plate box , or is it made of .125 diamond ?
.062 is fine
I disagree, especially for a street car, unless its maybe 6061, you can stick a screwdriver thru it, and you are not using a bladder, right? 15-22 gals exits a tear/puncture pretty quick, by the time the driver smells it, best if you are wearing a 3.5 fire suit. The weight difference is minimal going to .125" in the big picture, and your welder will be happier.
