teamsmith Posted January 1, 2016 Share Posted January 1, 2016 Hey everybody; it's been a couple of months since I've been on here but that is not because I've had a month of trouble free jeep ownership; rather I have had the truck parked in my yard while I procrastinated to deal with a fuel leak around the injectors and at the fuel rail. I bought and installed the full rebuilt kit for my injectors and that leak is fixed. However, I now get a drip drip drip from the FPR after I shut the engine off. Is there a way to rebuild the renix FPR? It's hard to even see where it has a seam that could have a leak. Would it be better to get an FPR from an HO model? You can see the drop of fuel on the bottom rim of the FPR. I cannot see where it is originating. Does the FPR come apart? Could it be at the connection to the fuel rail? At this point I still consider it undriveable until I'm no longer dripping fuel so any help is appreciated. Link to comment Share on other sites More sharing options...
Strokermjcomanche Posted January 1, 2016 Share Posted January 1, 2016 The connection at the FPR where it meets the rail uses the same O ring as the injectors use . It's more than likely where it's leaking . Link to comment Share on other sites More sharing options...
HOrnbrod Posted January 1, 2016 Share Posted January 1, 2016 And no, you can't use a regulator from an HO - different animal. If it's not the o-ring (try that first), and you need a new regulator, here's a link to shop around from: http://www.amazon.com/Crown-Automotive-83503635-Fuel-Regulator/dp/B009X1W3ZM Link to comment Share on other sites More sharing options...
teamsmith Posted January 2, 2016 Author Share Posted January 2, 2016 awesome. thanks guys; I could not tell that the fpr disconnected from the rail. i ended up getting extra orings with my injector rebuild kit so I'll get right on that. Link to comment Share on other sites More sharing options...
ScottJeep Posted January 3, 2016 Share Posted January 3, 2016 Like the part that Don has linked there. In my experience, yours may differ, the o-ring was not the same as the injectors. And it SUCKS when you cannot get that fuel line pushed back into the FPR. Always keep set of o-rings. I never throw one away no matter the age unless completely damaged beyond use. That policy saved my last FPR/Fuel Line "experience". Link to comment Share on other sites More sharing options...
Strokermjcomanche Posted January 3, 2016 Share Posted January 3, 2016 The feed line seal kit is 83502745 , but the rail seal is the same as the injectors . It's $6 for a complete injector oring kit if you want spares . I would never use old orings , It could lead to this . After all the exhaust manifold is directly below the fuel rail .

teamsmith Posted January 4, 2016 Author Share Posted January 4, 2016 Thank guys. I used the extra oring from my kit and it solved my rail leak. I used a plastic hammer to tap the FPR back into the rail, easy peasy. Now I can drive the truck with the pin pushed back into the fire extinguisher.
