    I'm leaking gas

    Every once in awhile when I would drive the car I would get a strong smell of gas.. Now it seems to be dumping fuel out the bottom. It starts and it runs and all the fuel lines on top seem to be ok... Any suggestions on what to look for?

    The fuel filter is under the car below the passenger seat. That's what was making the "whistling" noise on mine whenever it got cold. Replaced and all is quiet. Check connections to the filter if the leak is under your car (put down some cardboard to see where the leak is).

    It's coming out of the bottom of the engine bay near the fire wall ... It pours out near the headers

    There is only one fuel line that comes up there. The main line. Sounds like there is cut in it somewhere. Better get that figured out before you have a fire.

    If it is leaking near a header, I hope you're having it towed! Sounds to me like a return line.

    To add humor, my Wife often complains about the same thing with me...

    The return comes off the filter/ regulator near the right rear wheel. Only the main line goes forward from there.

    There is no return from the fuel rail? I can't say I've actively researched our fuel system on this car.

    No return from the rail.

    I found the leak seems to be coming from the top of the injector. I couldn't see it at first because the intake was blocking it

    Did you properly install the metal clip that holds the injector in place on the rail?

    Check for a pinched or nicked "O" Ring.

    Metal clip was the culprit replaced all of them.
