the one on the right is the one that is already there, the one on the left is new 13-ZG3 o-rings from Mazda.

what I pulled out:




and what I'm putting back in:




How come my new o-rings are so damn small? they don't look like the seal at all? Are these stock injectors? (they're primary's btw)

 

whooops wrong o-rings, nevermind IGNORE MEEEEEEEEEEEEEEE

 

wtf, these don't look right either :S

 

You need NF01 prefix rather than N3A1 for the lower O ring. Usually cheaper to source those non specific O rings from a hydraulic supplier I find.

 

my conclusion, mazda gave me wrong parts >.< these NF01-13-ZG3's are the only ones that came loose in the bag and not in the prepackaging. grrrrr

 

you need to get this stuff from mazdatrix or Ray Crowe at Malloy Mazda. dumbass local dealerships...

 

Apparently those plastic cracked caps can't be purchased separately either, there is no separate part number as the injectors are pretty much sold as a whole. I hope they aren't too detrimental as I don't plan on buying new injectors to replace those dumb caps

 

I would contact Keith at KGparts to see if he has any suitable replacements for the plastic primary pintle caps. If possible I would definitely try to replace them.

It looks like Mazdatrix only sells secondary pintle caps, I'm sure you could get some from KGpart as well.

 

A trick to removing and installing pintle caps without breaking them is to heat them up with a heat gun until they are pretty hot to the touch. You obivously don't want to get plastic too hot...

 

i never order parts from dealerships anymore for that reason. i asked for the drivers side door handle they give me the passengers. i ask for inner and outer water seals, they give me some seal the size of a tennis ball!!!???

 

actually... I have them listed for sale in the FS section. https://www.rx7club.com/showthread.php?t=739629

you are correct in saying that the primary FD injector has no replacement pintle caps. what we supply is a pintle cap from another vehicle that is modified to work with the FD primary injector.

 

looks like they gave you the upper o-ring from an FC
