What color are my injectors sopposed to be?? I called the guy at the nissan dealer and he said they have blue or black and my injectors are red?? And what is the cap called that screws down on top of the injector to the fuel rail??

 

They are red.

The cap is called a "Injector top cap"

The dealer is looking at VG30E injectors, they have a blue/black dot on them,

Make sure you specify you have a VE30DE engine when buying parts.

 

I cant find the injector top cap anywhere?

 

You mean you lost your cap?

 

no i Cant find them online to buy. two of mine broke when i was trying to install the injectors.

 

How in the world can you break the top cap?

 

how in the world did joo break the cap mang?


I have some extras if you want them, cheap

 

How do you get the injectors in the rail easily?? Can you use a different lube than gas on the top big oring on the injector to get it in the rail? I just screwed the cap down little by little to get the injector in the rail and it pinched the orings again and broke the two caps. Whats the trick to get the injector in the rail easily??

 

Yeah dude, you got to lube up both upper and lower o'rings with Vaseline before installing them into the rail..That's why you have been pinching o'rings..

I still fail to understand how you broke the injector caps..

 

do you mean the pintle caps on the bottom where the little o ring is??

 

If i lube it will the injector just push into the fuel rail?? and will the vaseline effect my gas cause it will get in it?? I broke the injector top caps because i couldnt get the injector all the way(no lube) in the rail so i just started screwing it down little by little switching screws and it broke.

 

there is a LOT of pressure coming out of those injectors, enough to push any vaseline (I believe they mean the petroleum jelly, not the hand moisturizer creamsm to make sure that is clear)out of the injector tip, and burn off somewhere in the engine. any "negative" consequences of using it will be gone a few seconds after running the newly installed injectors.

 

I believe he broke the metal covers on the fuel rail trying to crank them in.

 

I believe most later nissans use the same metal tops.
