Okay. I replaced my dead stock fuel pump with a walbro 255 LPH unit, and seem to have developed a fuel leak. I think it is from the stock FPR not flowing enough back to the tank to maintain the pressure.

Anyone else switched out their FPR?

A fuel leak? Where?

The high-pressure line from the fuel pump just past the filter. May be other places, but that's the main one.

I think you should replace that line before you consider the FPR.

And fix all the other leaks.

Unless something is very very wrong, the fuel lines should be sealing even if the pressure were higher than normal.

The lines are fairly new (less than 1 year old).

They aren't leaking in the middle of the line, but where they go onto the hardline on the intake manifold.

I'll try tightening the crap out of them tomorrow.

Also, my gas mileage has shot straight to hell.

Found out what the main problem was.

I'm sure that my fuel pressure is too high, but the reason it was leaking is that one of the fuel injection clamps screwed up and turned inward. This put a sharp edge to the fuel line, and also meant that the clamp wouldn't do so evenly.

I replaced the clamp, but the line was OK. I'll replace it later if need be.

Yeah, I thought it'd be something like that...

Why are you sure your fuel pressure is too high?

??

Okay. It probably isn't.


Someone who knows WAY more than I do had mentioned that may be the case, and I latched onto that as a problem because I don't have the equipment to validate or discredit that opinion.


You happy now?

I was just wondering... Sorry if I was rude.

You weren't being rude, I was.

I need to break myself of that habit. Once I can get to where I can take something apart and diagnose it myself, I'm usually pretty good about figuring it out. When I don't have the time to check, however, my mind latches onto some of the craziest ideas.

It just gets rather tiring when you are constantly wrong.

I know what you're talking about... When something's wrong with the car, it's really easy to get stuck thinking about one possible diagnosis, even if there's only weak evidence supporting that diagnosis. And then it's heartbreaking to "fix" it and find the problem still remains.
