hello
that was fast, I have A with the same engine, so ask me anything , anytime.
thanks
It's hard to say where the leak was, I have not seen any problems like this in NJ. fuel rail is one piece, you have 6 injectors (with 6 O-rings) and fuel press. valve with O-ring. More like it one (or more) started to leak.
this is going to sound crazy ,but I would park it outside and wait until it happed again to see where the leak is.
good luck pltech
Answerhello
very easy, what I do is , I take out 2 bolts that hold fuel rail on one side and lift rail on the one side only. take injectors out and replace o-rings. put some silicone or any grease on o-rings (helps to install it back) When you done with one side reinstall 2 bolts and go to the other side. be carful ,You may have some fuel pressure in the system.
good luck Greg
