Question about 1990 Nissan 300ZX
I recently installed 6 brand new fuel injectors on my 1993 300zx NA. One of them leaked. When I took the injector out the o ring was torn I replaced it and it happened again (same thing it was torn). What could I be doing wrong? Mind you after each time I installed the injector it did not leak immediately but started leaking after I test drove it.
You need to lubricate the o ring prior to fitting the injector. Without the lubrication the injector does not slide into the fitting and can roll in the groove and get snagged and damaged. A thin film of engine oil will fix it but also check the sleeve where the injector sits in case it has a burr or was nicked during the removal process first time.
