ACDelco O-Ring Kit, Black Rubber, Fuel Injector O-Ring Kit, 1 Count, 1 Pack

Installed these on a 2002 Chevy Silverado when changing out intake manifold gasket. replacing these seals added an extra 20-30 minutes to whole project but I'm glad I did it. You won't notice any improvement in performance per se, but more piece of mind for me. Used a small pick to take the old ones off and slide these into place using just my fingers to ensure I didn't nick the seals. They fit just like the originals. I have put about 10K miles on the truck since replacement and have worked well. Truck runs much better, but that has more to do with replacing the intake gasket and cleaning the injectors. Note: If your trucks idles rough in colder weather until warm, the intake gasket needs to be replaced. Colder air is more dense, which amplifies the unrestricted air flow impact.

Great Value, works as should. No leaks

Should of taken picture but I received good o rings not sure if the other guys either tried to rip off GM or genuinely got used / dry rotted parts anyways they seal and work as intended the fatter blue orings are for fuel rail and smaller brown ones are for bottom of injector to intake
