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?
