Problem with Roe fuel rail seal

[Smokin' 2]

Hello everyone. My Roe install was humming right along until I got to sealing the fuel rails. When I primed the system I leaked where the injectors seat in the rail. I already replaced the o rings on my used injectors (They were used and Sean recommended replacing the o rings to improve the seal).

I also used some bearing grease as Chuck Tator recommended when discussing the installation with him. Both gentlemen have been great.

I'm on the verge of turning in my 'gearhead card' and hauling her to ART incomplete for them to solve the problem. I planned to have them optimize the tune for me after I completed the install.

Can anyone save me from the 'trailor of shame' haul to Austin and help get me out of this with some advice?



Thanks in advance

Do you have the large metal flat washers at the bottom of the injectors? I think those are there to keep the injector from seating too far into the intake manifold when you push the fuel rails down. If they are, you might try adding another one.

Been there done that several times. I now check the fuel system seal before I put the rest of the system on. Basically its just a matter of ensuring proper alignment as you press the intake tube/fuel rail assembly on top of the five injectors. Very easy to cut the top O ring. Replacements are from a 96 Mustang V8 (If you go to NAPA). Lube them up as suggested and gently rock the fuel rail over all five at the same time while pressing down gingerly. If they are all aligned, the assemplly seats pretty easily and you can tell its on by the amount of threads showing on the four threaded studs poking out. When at this stage, tighten one stud down a bit and hook the fuel line up to the rails and turn the key to ON to pressurize the rails. If all is well, complete the install. It can take a couple of times to get the technique down, but YOU CAN DO IT!!

You should be able to freely move the injectors under the rail by reaching in with your fingers and twisting them a little. If any don't move freely, that could be a trouble point.

I just replace the o-rings on my injectors. Their were 2 different manufacturers that I had to get, because the store only had 4 of one brand and 6 of the others. The one brand was a brown seal, and the other was black. For some reason, 3 of the 4 black ones leaked, and none of the brown seals did. I looked at them and they seemed to be identical. I was at a loss, so I ordered more of the brown o-rings and no more leaks.

It takes a gentle touch when installing the rails. Lube them up and go easily and you will be fine.

Thanks for the support and ideas.

Steve, your write up was very helpful. Everything that was a problem up to priming the fuel system for you went smoothly for me thanks to having your information. I was waiting for 'success' to update you.

I'm embarassed that this has taken so much time already. I'll take a deep breath and try a few of these techniques this afternoon when I get home from work and see how it goes. I didn't anticipate this part of the install being a problem

Got it. Everything primed without a leak.

Thanks everyone for the help.

Good job! Glad the write up helped. Makes sure the main fuel line connection is snapped in good and tight. I had an issue there as well. Idling in the garage ... no leaks. Maiden voyage with the frame flexing from my slanted driveway to the level road....that connection wasn't as secure as I thought.
