I've built a few gas tanks and used .125 3003 aluminum. I remember it being heavier than I expected. Just courious to hear what material others have used to build gas tanks. I would think a thinner material would be ok just didn't have the ***** to try it.

 

we used .090 for our s2000 powered sandrail and for our 34 ford blown hotrod. i wouldnt go any thinner than .090

 

Hey thanks for the reply, what type of Aluminum did you use? 6061, 3003, etc?

 

5052 or 3003 either in the half hard heat treat 3003 is easier to bend using 16ga rated equipment both weld with 4043 tig wire
