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