Question

What does it signify when you can detect a gas odor from a vehicle after it has been switched off?

Answer 1

You have a fuel leak or fuel vapor leak. It should be checked out and repaired. It may get worse but it certainly wont get better. Could be anything from the gas cap, filler neck, fuel tank, fuel lines, filter, even the injector or carburetor whichever yours has, also any of the evaporative lines could be leaking.

Answer 2

There may be a leak possibly pinhole size. Unless there is a visible spot under the car, It's probably nothing.

Answer 3

it means you gotta leak....thats terrible too, coz gas costs too much to waste

Answer 4

Probably the Cannister that takes care of Fumes, as the excess gas is returned to tank from Fuel manifold.

Answer 5

It is possible that you have a fuel leak. You do not say what type of vehicle it is, nor the age. It could be a mechanical fuel pump going bad, a leaking fuel line or fuel filter, a carburetor problem, a fuel injector problem, a gas tank leak, or a evaporative emissions system problem.. . Of course all cars do not have all of these things. Have your car checked by a qualified mechanic. Leaking gasoline is a very dangerous thing. If gas comes in contact with a hot exhaust system part, things could get very hot!!!!

Answer 6

your line is shot my car and my grandmothers car had leaks like it in it i just replaced the hole thing

Answer 7

Your fuel cap may not be venting as it usually should, and it may have blown the seal on the cap, resulting in smell of gasoline. Just a thought...

Answer 8

i won't light a cig near by

Answer 9

the only reason your not smelling it other times is because your moving.When you done driving and the engine is hot open the hood and look for a wet spot.It will evaporate very fast so leave it running.Your driving a bomb so get it fixed.. I see some said dont smoke.The cigarette wont set the gas on fire.But the match will.
