These are the 3 O-Rings that fit my 2000 Chevy Tahoe 5.3L engine. There is a fuel rail that crosses over top of the engine. The cross-over fuel line has a torx screw with a hold-down bracket keeping them secure. When I cleaned my fuel injectors I failed to put my old ones back in properly. Like other have said, the key to replacing the O-rings is to put a light coat of new motor oil on them to make the o-rings easy to put in the female end of the fuel rail and the male end to slide in. The O-rings seem to swell/expand when in contact with fuel (likely to make the seal) so motor oil works the best to get the new ones re-seated. Careful not to drop the o-rings once coated in the oil, they are slippery & kind of expensive!A picture of my drivers side OLD O-rings are included with this review. The new O-rings matched up perfectly.

Saw one review saying it worked on tbss/nnbs crossover took the risk and they do fit. Expensive for 3 o rings especially when you are only using the two for the tbss/nnbs but they are authentic GM so they are good quality.
