Broken injector tip!
I was working on replacing an intake manifold gasket that was leaking coolant, and the nylon/plastic tip of one of the injectors broke off as I was removing the fuel rail. I managed to retrieve the broken piece from down by the valve stem, but am not sure what to do about the injector. I haven't found a source for that particular piece yet, though the entire injector is about $66 or so from the dealer.
Injector tip with and without the plastic piece:
Any ideas on 1) where the plastic piece could be obtained, 2) how important it is (beyond keeping the o-ring in place when the injector is removed)?
