Pulling Fuel Rails and Injectors

[A26B]

There is something odd going on that will need some clarification and/or photos.

1. Your signature indicates you have a 1995 ZR-1
2. Only 1990~92 models have the seal in the injector housing for the primary injector.
3. 1993~1995 LT5 engines have the same o-ring seal on both the top & bottom of all 16 injectors.

If your injector housings have an o-ring seal in the primary injector bore, then you have either early injector housings on a late model engine (replaced at some point after manufacture) or the engine has been replaced with a 90~92 model.

You ordered the 93~95 pkg which would not include the lower seal for the primary injector, PN 10067600-V.

A note regarding re-use of original fuel system seals
I am opposed to re-using the original o-ring seals, especially in the fuel system, regardless of how careful one is or how good they might appear to be. I have never been able to determine what material the original seals were made from, so compatibility with modern, ethanol blended gasoline is questionable. Regardless of the compatibility issue, original seals are now at least 19 years old. The seals take a "set" and also do not have the compressibility as when new. For the small difference in expense, it's simply not worth it to risk a fuel leak or trying to hunt down an difficult vacuum leak (in the case of the lower injector seal).
