Hi, l have an old subaru impreza that has a strong gas smell. itwas smoked, but that same day it was smoked was about the only day l did not smell gasoline, of course they could not find anything.

any tips on what l can ask when l take somewhere for repair?
thanks!

Could it be a leak at the gas tank? If the tank is filled above
the 'hole' then after some time it will disappear (once the
gas level drops in the tank).

If u notice the smell, try to determine if it is coming from
under the hood, or from the rear of the car.
Also, check for something dripping or wet.

This is a dangerous problem, if not found soon it could result
in a fire. If u take it to someone, fill the gas tank first, it
may help them determine the problem.
