Work in progress.
Basically I had a nice little leak coming from the bottom of the fuel pressure regulator. Turns out the gaskets are getting old. Well _DUH_ they were put in sometime in 1993.

The most important bit in making this easy is putting the new O-rings into the rail, then sliding the regulator in. You will NEVER be able to push it in to the high pressure side the other way. The outside ring slides in easily even if you leave it on the regulator. I forgot to move it after taking the picture and it went in without a fuss.

Do remember to use some oil on the rings or you can tear them.


Some day I will put thumbnails, but for now here are the pics.

You can see in the oringob image that the outer ring is not only flat but cracking.

The vac-on and vac-off show fuel pressure on the rail with the vac line connected and disconnected. If your jeep doesn't move when the line is off then the regulator has failed. That's a $100 part!!!!.

As it is, the rings cost about $12. But I suspect you can get them cheaper. I sort of needed them TODAY as, well, dribbling fuel on the header is a bad thing, ok.......
