I am still building my 41 chevy truck and recently removed the tank and found that there was gas seeping out just enough to keep the dirt and rust inbetween the tank and the floorboard wet. Not a good thing!!

It was not noticeable from above or below while the tank was installed either. I already knew it was in a bad location but after seeing that there is no way I would keep the tank in its stock location!

I bought an aluminium fuel cell I am going to mount behind the cab.

I think those pics gmc248 posted are the work of "phat" who can be found on http://www.roddingroundtable.com
