Due to variances in injector lengths, fuel injector adapters & manifolds - ALWAYS verify fuel injector fitment for proper injector O ring engagement. Fuel injectors should not move up and down MORE than .070" - If your application has more than .070" MMR will gladly exchange the rail brackets to achieve the correct engagement. Operating a vehicle with improper Fuel Injector O ring seal engagement is a leak & fire hazard!
