I ordered a gas filler tube grommet today on ebay, tomorrow I plan to drop the tank. I crawled under to inspect. Looks pretty yucky under there!
Dick, I saw where you advised Rob from Michigan:
I was thinking that with the gas tank drained, connections removed and straps removed - it might be possible to break the filler tube connection by twisting the tank. What are your thoughts about that? I think it’s going to be tight to get a strap around that tube.
While I was under there, I tore off a piece of the material between the tank and the trunk floor:
I like Dick’s idea of doubling up on roofing material for this - I think that should do nicely.
