Hello everyone:

Thanks for all the help.

I fixed it!

I disassembly the valve and the o-ring was gone. I changed it for a new one and now the leak is gone!!

So now I'm gonna focus on the preventive maintence with the injection system so I want to ask a help again.

As the car has passed the 100k kilometers on the ODO (approx 134k now) I want to avoid others issues as the long star (FPR issue).

I searched the forum for the FPR part number but I couldn't find. Does anyone knows what is the FPR part number?

Thank you for your help!

 

That's where you check the fuel pressure - there's a valve under the blue cap.

 

Hi hoonk, thank you for your reply. Is possible to dissassembly this part or it is one piece with the fuel rail??

Thank you for your attention.

 

There is a valve, same design as a tire valve - under the plastic cap - if that's where it's leaking - the valve core might be replaceable.

 

Sometimes that type of valve (Schraeder) can be "reset" by just tapping the center "pin" to open it slightly (which will, of course, release some gas - be careful). Sometimes that's all it takes to re-seat the seals, and - since this isn't a valve that gets used very often - you might have permanently fixed it. I'd just take the cap off and prime the fuel system by turning the key on (without starting the car) to get a feel for how much fuel is leaking, then try tapping the pin to see if it stops.
