Problem filling fuel tank. Back air flow issue thru fill neck vent pipe. Very slow to fill. What could be the problem? ---

Been there, suffered that, fixed it by replacing the charcoal canister and the purge valve while I was under there. Fixed it right up. About $125 in parts. Took me 30 minutes, maybe. ---

Just filled on slow, no cost for 12 years.
