My son just purchased a 2003 Impala and is having a problem when trying to fill up on gas. The gas pump nozzle will shut off after 2-3 gallons even though the fuel level is still very low..We have tried filling up at several stations all with the same result. If we continue to pump 2-3 gallons at a time it does eventually fill...I figure there is a vapor lock in the tank and there is a problem with the vent hose or cannister.
Another thing, it appears the the gas cap is not the original for that car as it is not attached with a plastic tie as in most cars, so I'll go to the dealer and get the right one.
My question: Is it an easy affair to replace the gas tank vent hose, or does the tank actually have to come out to replace it?...any words of wisdom would be appreciated.
