quick injectors question..
quick injectors question.. reinstalling injectors. one of them is missing the plastic lock or whatever it is called. can i reuse it without this or is it a must? can i install them with 1 missing or should i remove them all? the 8 o rings are in great condition though..thanks!
its def not metal if am right..it sits over the O ring (from the intake side not the rail side) it keeps the rubber o ring in place.
EDIT: its the o ring retainer if am not mistaken...comn guys ill have this installed in the morning!

hmm i have no idea. i don't think it would be a good idea, but i'd try it without if i needed the car. it's not hard to pull the rail and you'll know as soon as you turn the key if it is leaking or not.

Honestly, for a temp thing, I'd run it. It doesn't alter the O-ring so no the injector will not leak. Downward pressure is what actually keeps the injectors in-place and sealed. I would however, source another injector and scrap that one at the first opportunity.
thanks! holidays are on here for 10 days 
i wont find any autostores opened plus i honestly dont want to go thru this again! its really a pita plus my intake is off already so ill do it all once. looks like am going to do it and see how it goes.

The bottom ring does not seal against the 59 pounds of pressure from the fuel pump anyway. That would be on the rail side of the injector. You just need that oring to seal against vacuum leaks and such. There is a lot less demand on the lower o-ring, and again, that retainer won't effect it, at least in the short term.
