Fuel Injector Seal Set. Fits 90~92 ZR-1 LT5. 24 seals are required. Sold by the set of 24. Not sold individually.

This Viton-A 75  o-ring fits onto the top of all primary and secondary injectors AND also the bottom of the secondary injector, for a total of 24.  Viton-A is better suited and therefore more resistant to failure than Buna-N for modern fuels such as Sour Gasoline & Gasohol( Unleaded Gas /10% Ethanol).

Note: The primary injector "lower" seal, PN 10067600-V, is inside of the injector housing and should also be replaced.
