Any idea why the fuel shoots back out the filler neck when attempting to fill at gasoline station. Get about half a gallon in before the fuel literaly comes gushing back out. Tried throttling the pump nozzle, doesn'rt seem to help much. Is there a vent tube blocked or crushed maybe? Only a pressure feed and return from fuel pump in-tank module. Is there a vent that is hosed to a vent solenoid that might be stuck shut? Get no codes of any kind.
Re: Trouble getting fuel to go into tank - '98 STS
that's what i am thinkin'... evap solenoid near the tank that runs to the charcoal canister. I had a Venture van fuel module I replaced for the GF's flower shop delivery van that had a decent sized hose attached by screw clamp to a nipple at top corner of tank. It was a real pain to get to, had to hold tank with floor jack half-way up then do the "feely thing" at arm's length with the air powered nut driver, as hose wasn't long enough to do while tank was on ground.
