I'm going to change out my fuel injectors on a 1994 Maxima (SOHC). I don't know which it needs, the Green Mark or Yellow Mark. That's what the online store asks for.

 

you'll have to check your injectors and see which came on there. if i remember correctly you can use either color as long as all of them are the same (no mixing up colors). i'll wait for someone a bit more savvy with the injectors to chime in on that though.

 

That is correct. the color does matter. It indicates flow rate.
Just keep them the same color and you will be ok. The paint mark will be on the body of the inj near the electrical connector(you may have to remove connector to see it).

 

if your gonna replace one and do it yourself then i reccomend just doing them all at the same time, if you have enough $ though. I remember doing this myself and when i was done taking it all apart i decided to just get all new injectors, because i didn't want to do it again for a while.

 

Thanks a bunch! I'm going at it. Wish me luck. I'm trying to keep the old Max running, it still has a great body!!!

 

I sell the injectors.
