I wonder if it could be a badly connected filler hose coming from the gas cap pipe? Or vent tube hose.

I know I had something similar, some shmuck had used the wax ring you use under a toilet when you install a new toilet to try and seal the gas tank hole that the fuel pump/gauge goes in. Instead of replacing the gasket.
