Fuel Rail Disconnect O-Rings Broken

Recommended Posts

Before re-connecting the fuel line to the fuel rail inlet, I verified the o-rings looked and felt in good condition. After connecting the fuel line and priming the fuel pump, it started to leak. Removing the fuel line revealed two busted o-rings (one missing in this pic). I would suspect that I just need to replace the o-rings, but I wonder if I'm missing something else here... :confused: , because I would guess that if I just replace the o-rings will the same issue happen again.




The service manual mentions some repair kit that comes with a disposable plug that you are supposed to replace whenever you disconnect any of these quick disconnects. Does that apply here? Should I just be able to install two new o-rings, and are these o-rings indeed 3/8"?




Thanks a lot.
