Accel & Multec Injector ??? - ZR-1 Net Registry Forums

32valvZ · 01-31-2008

Got all my parts in today (thanks Jeff) & see theres a difference in the factory injectors & the Accels. The primaries on the Multecs dont have an O ring on the tips & look different from the secondaries which DO have an O ring.

The Accels look exactly the same & both have O rings. Do I remove the O rings or leave them on (primary side of course)?

Well, I don't know if it was right or not, but the Accels I put in, I just put them in. O-rings and all.

Now somebody's going to tell me I have to take it back apart. :P

on 92's & up you shouldn't need to do anything concerning O-rings with the Accel's, individual pt. no: 150121 or eight pack no: 150821. you might need to use a razor blade to remove the plastic guide for the injector harness clip. it's just a guide, the harness will still clip in place by using the tabs on the sides. the guide was so the primary & secondary were not swapped.

The part # is 150821 for all 16. 2 8-pack boxes. The original primaries had no O rings, these all have O rings....Jeff already trimmed the tabs for me, so, no problem there.....

Throw them in and forget about it. Make sure the C-clip hits the first indentation making sure the injector gets fully seated.

And yes, your coils were trimmed and numbered, as were the tabs for the injectors.

Ive always heard Jeff offers full "trim" service

I don't understand, so you all are saying you leave the spray-end o-ring on the injector? It won't be held in by anything except the o-ring's tension. I'd be afraid one day it might fall off and get sucked into the engine.

I used '93+ injectors and here is what I did to them prior to installing:

Aurora, that was my reasoning as well. Thats why I questioned it. I might take them off too, its just my luck & one will fall off.

The 1990 primary injector has an "O" ring that sits inside the housing body. The "O" ring fits around the injector body providing the seal. These are about the size of a quarter and no longer available at GM. If you need some let me know I can tell you where to buy them, cost is about a dollar each. These are made of Viton material, same as the original. GM price on these was $25.00 each.
