Theoretical question here. I came across a fuel tank Gm20b that someone said could be trmporary replacement for the tank in my starfire 64. Is thete truth to this? The filler hose and vent tube connections look to be on the proper side.

 

"Someone " was wrong .
This tank was meant for mid 90's GM cars . No way , it will fit or work in a 64 Starfire .
