Quick question, 89XJ, 4.0L, tearing it apart to replace the exhaust manifold. Got the injectors taken out and decided to order a new o-ring kit from RockAuto. Got it and there's 13 rings total, (6 for the injector-manifold seam, 6 for the injector-rail seam, and 1 for the rail itself). Thing is, they are all brown, whereas the original ones had brown rings for injector-manifold and black rings for injector-rail. FWIW the Hanes manual says an o-ring kit should have 6 brown rings and 7 black rings, and that the black rings are a different composition.
I can't imagine they would have packaged 13 of the brown rings if it wasn't OK to use them, but I don't want to mess this up. Am I best off just to go to the stealership and get a proper O-ring kit? Need to go there to get the fuel supply and return quick connects, anyway...
