Does anyone have info on how to properly rebuild/reseal an AEM fuel rail? I've replaced the o-ring on the side where I was getting a fuel leak, however, it doesn't seem to have helped. The o-ring I replaced was completely destroyed - but the replacement o-ring came from an o-ring kit I have.
Measurements (P18):
ID:17.8
OD: 22.6
Section: 2.4
Is the o-ring that AEM uses especially thick? Does anyone have the dimensions for the AEM o ring(s) that sit inside the fuel rail?
This is the fuel rail being discussed:
Also for anyone looking for an AEM specific o-ring that stumbles across this thread:
Edit:
So I've stumbled across my answer in the form of the PDF from AEM linked here ( AEM High Volume Fuel Rail PDF Mitsubishi ). However, I can't find the specs for it anywhere.
There are two o-rings that sit in the inside pictured here:
Part number: AVM-1-3024 ( AEM )
This is the o-ring I initially replaced but will be pulling it back out (marked in red).There's a shoulder here that looks like it would hold an o-ring but according to the PDF, the only o-rings (2x ea. side ) sit inside of the rail rather than on the swivel piece.
All parts included in the AEM kit:
Edit: Will be pulling it out again today and I'll edit the thread again if I have useful information. Otherwise, I'll edit out the questions and leave this for other people that need info on these pieces of garbage. I wish I had a 91-94 fuel rail laying around I'd much rather run one of those since I don't plan on running nitrous.
