Default ls1 injectors

I just picked some up off a member here and on the tip of the injector right next to the gasket one of them the faded skinny red ring is missing. Can this affect anything? Thanks

Please post a pic. If its the o ring missing yes you should replace it. They about $8 for a set at the auto parts store.

First, set your camera to close ups by pushing the distance button until the flower pops up

Next, thats the pintle cap and is easily replaced, just snap a new one on. NAPA carries them along with pretty much any injector service/sales company

You need that to keep the seal on the injector. If you dont, it will fall off and get sucked into the engine when under heavy vacuum i.e. idle, then cause a massive vacuum leak. Since you're already messing with them, it'd be a good idea to replace all the O-rings too
