Fuel Rail Disconnect O-Rings Broken

[Jargon]

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...  , 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.

I've never encountered any disposable plug. Just the two o-rings separated by the plastic spacer. It is a rather snug fit and I have damaged perfectly good o-rings upon installing when I have not been careful.

Get the Mopar Repair kits, they work best:

The disposable plug is the white middle section.

Installing o-rings dry is asking for them to catch, roll over, and split/tear.

 

I use light silicone grease most of the time, but a drop of clean motor oil or even a tiny squirt of WD-40 will save you a lot of trouble.
