Greetings everyone. Lately when refueling my Thor Quantum rw28 it acts like the fuel tank vent is blocked somewhere. I can only pump about 1 gallon per minute without it backing up and shutting the gas pump nozzle off. I looked under the coach to see if I could see any issues but everything was intact. I see that the refill line is not very big and makes a couple 90 degree turns. Any ideas? Thanks.
Thanks. The main house runs down toward the tank. I am assuming that the tank vents into some type of canister in the engine compartment so I'll check there too. The vent line at the tank is all intact so I don't think a mud dauber made a nest or something like that.
