    Injector rebuild

    Hello everyone. Posted this message in some Facebook groups regarding nismo 555 yellow injectors. I would like to know if anyone knows how are the little "lower filter" black parts called and where can they be bought? The ones just above the lower oring.
    Also, do you have to remove the plastic part on the spray nozzle to install new orings? If so, how is it removed?

    Cheers.

    Thanks for the reply, buddy.
    But I meant the black piece that sits just above the lower oring. Looks like a little black round filter, as it has some windows in it.

    Ahh that's the filter itself. Most service kits are a complete set, example: https://www.nzefi.com/product/nissan...it-4-cyl-sr20/

    Thanks a lot bud. We replaced just bth rings and when fuel pressure is applied to the rail, they hold pressure ok. No fuel leaks (with the rail off the intake manifold.
