About 10 min after I turn off my engine, there is no more pressure in my fuel lines. I have a fuel pressure gauge, and I've checked extensively to see if I could find where the fuel was leaking from. Would the fuel filter or some other part cause the fuel to leak out? A little pointer would be great.

where is it leaking from? filter? FPR? Fuel rail? Injectors? Gotta find the leak first.

 

That's just it, I cant see where it's leaking from. If the injectors are leaking into the engine or something's just not holding the pressure, then I wont be able to see the leak. I guess I just want to know how I can check to see which thing is leaking when I'm not able to see the leak, or if anyone who has had a similar problem give me a heads up.

 

don't know, my fuel rail was leaking before, but only when my fuel pump was on. it was easy to find. in your case, idk.

 

if no external leaks. it can only leak from the injectors, fuel regulator not holding pressure, or fuel pump check valve bad.

for the regulator take some pliers and clamp the return hose right after you turn the engine off. with a gauge pluged in if pressure holds then its the regulator diapham bad. normally after 10 min. pressure should drop up to 10 psi.
