Hi All

 

I am looking for an injector rail for my 1990 300ZX NA. Managed to break the plastic tip off one of the injectors when stripping down and this is the only thing stopping me from rebuilding my engine.

 

If anyone knows of where I can get hold of one, I would really appreciate it. Not sure if it is a 270cc or a 370cc rail, it's a standard 1990 import.

 

cheers in advance

 

best wishes

I'm confused, why do you need a new fuel rail if the plastic part of the injector has broken?

hi all

where can i get the plastic end cover for the injector?.having problems getting a nissan injector didn't think i would have any chance of getting just the plastic part.

cheers

Hi Trev, you can get the pintle caps separately.

Though I suspect you could probably get one in the UK, maybe from a used injector. They’re the same for both early TT and N/A injectors.

hi folks

next question.does anybody have a spare printle cap please?

thanks

These should do the trick, ask the seller to confirm:

They measure pintle shaft size of 7.8mm, hole size of 2mm and a length of 13.8mm. You can check this with your injector.
