Fuel Injector Orings

[relyt120]

So the injectors on one of my trucks have always leaked a little from the previous owner. Finally got tried of the fuel smell in cab so decided to change the o-rings.

Looked in the Haynes manual and it says the kit should include 7 brown and 6 black o rings (or the other way around)

With the brown going on the tip and the black going on the rail side.

It very explicitly states that they are not interchangeable and designed for different purposes.

I track down the mopar part no from a diagram online 8503637. All seems correct.

Find a dealer who says they have it.

Drive 25 miles out to get it and the plastic has 12 black o rings!? With a hole in the bag. I'm assuming one fell out...

My question is will these black ones work for both ends of the injector despite the manual? Anyone use these?

On Saturday I replaced my injectors, when doing so I used the exact same o rings on both sides of the injectors. Has been leak free since, everything seems fine so far.

I recently did mine and it had brown and black and I got mine from napa.

I just picked up and installed the kit from the dealer and it still leaks...and now I have screwed up the return line oring so its leaking too  :doh:

Leaking from the fuel rail side. 

I had picked up a few spare injectors from the JY to replace a mismatch from the previous owner and I know at one point they were the ones leaking but that was before the new orings and now I can't tell them from the originals :dunno:

I think I might try to find a replacement fuel rail.

 

Any thoughts?
