It does this when its running OR off. Is this normal operation, or is it a problem?
Symptom: Car runs, car gets turned off, you go to gas station, MUCH air hisses out of the cap when its opened.
The gas guy thought the tank was near empty, it took 10 gallons. Fuel gauge was at a quarter, or so.
Is this a problem, or is this what gas tanks do? (It also does this when it is off.)
*This is an ANY CAR question, not only specific to my Taurus. Cap and everything looks original.
Thinking of getting Gumout, but my tank is full now, so nit sure how well it would work.
