Fuel leak engine bay

[turbo55]

The O-rings for the rail side are identical to the intake side. When I got mine cleaned by MEPEH he replaced both sides, so I didn't need to get any new O-rings for them.

Yeah I doubt the rail itself is leaking. Mine was a bit rusty (surface rust) when I pulled it so cleaned it, took a wire wheel to it, and primed+painted it. Although I made sure to completely seal it off before doing any of that, I taped off the fuel openings and vaccum opening, and I put 1 of those clear adhesive rubber bumpers into each fuel injector well - they're the perfect size. Afterwards you can use a drywall screw to get them out.

So he will clean the rail too? As well as the injectors?

If that's the case, I'll order the rail and injectors from him and ship him my old stuff as a core.

I believe I've spotted the leak, it's the hose that's connected to the fuel rail. I'm going to go ahead and replace that one and the one connected to the FPR. Any others I should replace?



Also, does the motor sound healthy?

No you clean the rail yourself!

Other than engine bay fuel hoses, you might want to take a look at the little bits of hose coming to/from your fuel filter (under the car in front of the driver's side rear wheel).

I think you have an odd sound, the one that's about every half second, like the rubbing or suction sound? If it's rubbing it could be one of the belts, is its suction I'm not sure.

Nice Delphin!

I'll go ahead and buy the injectors, hose and new fuel filter and see how it's running after that.

As for the sound, it pulls hard and smooth but definitely sounds different.

And thank you!

Has anybody else heard this noise from an M20? It's getting more pronounced it seems.
