Default Re: 1931 Gas tank install

I just installed my late 30 tank in my coupe last weekend. Used some clear RTV to hold the anti-squeek welt to the cowl and firewall. That way it does not move when installing the tank. I too cut slits (about 1 inch apart) where the curve begins on the tank at the cowl. Used some strips of cloth stapled to the slits to help pull it snug and up against the tank.
Followed the same steps as JW mentioned above with installing the tank screws. Ended up using some needle-nose plyers to pull specific spots of the tank welting to make it snug at the curves. Once I had the whole tank installed and the cowl welting pulled snug, then and only then did I cut the welting to be hidden under the cowl band.
Took quite a bit of time for me since I was by myself and wanted to ensure it was right the first time. Good luck!!
