So one of my injectors is leaking from the lower seal. They're RX-7 low-z injectors which have a wider pintle cap than the Miata injectors do. I'm currently using the RX-7 lower seals, but need to fix the leak.

I'm pretty well done fabbing a new set that will use standard o-rings to seal the injectors to the head, but don't want to pull my injectors out to measure the thickness of the lower seal if I don't have to. Anyone happen to have one lying around they can measure for me?

I measured an oem insulator (JE06-13-257) to be 5.50mm/0.217" thick.
