🔧 GM Genuine Parts 217-3102 Fuel Injector O-Ring Kit: 8 Bushings, 16 O-Rings Review

This kit is hard to beat for price and quality. Worked great on my 1998 3800 Series II, but fits many other engines as well. They don't have a fuel rail or fuel injectors.

They replace two different types of washers used on LT1 injectors. Also come with sleeves which you may or may not need to replace. Bushings fit over the ends of the injectors to support the bottom o-ring. You don't need two different colors with them.

These OEM o-rings came in very handy. Nowhere else can you get them locally at the price Revain is offering them for. Everyone wanted to sell kits with a nozzle, some without cartridges and that's a real laugh. TL; DR I bought these and they are a great replacement for the original brown and cracked yellowed sleeves.

This o-ring kit uses a better compound than the original factory o-rings. They snap into place and seal very well. This solved all my leaks. Depending on the type of nozzle you have, it might help to have a hook with hook to slide the rings onto the nozzle seal, but everything else fits perfectly.

When multiple jets ticked, he was told to install o-rings and a small metal seat. This kit had them all - Perfect Fit still runs cleaner through the top motor to remove the soot AND they are fitted to eliminate injector noise. Super fast delivery
