Hi guys! I've had an injectors leaking problem this winter and replace them all with rebuild one. But now, when I start the gaz pump, their is still a leak. It seem to come from somthing attach on the fuel rail(round and got something plug on it that plug into the upper intake), it's just over the last injector in the back, passenger side. There seem to be no gas leaking and no strong gas smell though... I think my fuel rail are aftermarket since they are chrome finish.
Anybody knows this part name and if it's normal to here that leaking pressure noise.(sorry guy my english is pretty bad haha)
Thank you!

 

The factory fuel rails have a shiny finish. Usually the aftermarket ones are machined aluminium. It sounds like you're looking at the fuel pressure regulator, that would be on the right rear on a Fox. Either the seals between the regulator and the rail could be leaking, or it might be the diaphragm inside the regulator.

You could buy a new OEM regulator from Ford if needed, or get a good used one. They don't go bad too often, and there should be some around from people who have gone to an aftermarket adjustable unit ... or you could consider buying one of those for yourself. If it's just the seals, you should be able to order them through your local parts store.


cheers

hope the fix is easy, good luck

 

I was totally just going to say that.

 

Was thinking a shim issue if it had to just do with an injector.

Fast Ed has it covered.

 

^^when doesn't he tehehe

 

Me too hahaha

 

Thank you guy, your knowledge is very appreciated! I hope it's just an o-ring problem

 

I got that fuel pressure regulator out and found poor o-ring and gasket condition. I replace them with brand new one. There is still that pressure sound comming out of it while the pump is running, I guess it's normal since there is fuel going through it and there's no gas smell... well I hope lol, what do you guys think about that?
