Replying to: danylle (Nov 06, 2009 2:19 pm) Why do you believe it's leaking gas? What are the symptoms?   There are places on an engine where gas can leak. There are connections on the flexible fuel lines at the fuel rails that holds the injectors.   There is a FPR (fuel pressure regulator) which controls the fuel pressure based on engine vacuum, sensing the demand for power from the engine. These in some cases were recalled because they could leak into the vacuum tube connected to them and let raw fuel get into the intake manifold where there usually is only air; occasionally a spark would ignite that mixture and the upper intake manifold would crack from the pressure inside.   There is raw fuel at each injector. There are o-rings around each injector (two) and these might leak with age allowing raw fuel to seep out.   Your brief description sounds like you are smelling gasoline and believe it's in the engine compartment.   You also can have fuel leak at the metal line from the gas tank which is under pressure by the right rear tire.   You also can have a fuel leak at the fuel filter in that line from the tank. The fuel filter is under the rear passenger's right foot. It's about the size of a caffeine drink can (Red Bull?). the connections there might be leaking.   At the back of the car rust is a major problem if the car doesn't get sprayed off regularly when the car gets salt underneath in the winter in the northern parts.

Replying to: imidazol97 (Nov 07, 2009 6:28 am) i saw the gas coming out thats how i know its in the engine compartment. I got the leak fixed today turns out it was just a small clip that was broken instead of the whole piece which i also figured out what that was by searching through catalogs at my work (schucks). now I just need to figure out why my car is "sputtering" when you accelerate from a stop. since there are quite a few things that can cause it im starting small and working my way from there. If anyone has suggestions that could cause that, that I may have not thought of yet that would be helpful also. I just bought the car so im not really sure what has been done recently, I just changed the plugs and that is all I have done so far.
