I recently bought the KG fuel rails so i can run a full SS AN fuel setup on my s4 TII.. i got 1600 cc injectors for the secondaries and they fit good but i was gonna use my GSL SE injectors for the primaries but i went to put them in and there way to small to fit into the KG rail..so my question is what do i have to do to make these fit? do i need to buy differnt injectors?

 

Mazdatrix sells some grommets for fuel injectors. That's where I ordered mine from.

 

You can try Autozone and just get some bigger O rings. i was having the same problem. I ended up just going with 820cc primaries..

 

i looked on mazdartix and couldnt find anything...its gonna take alot more then a o ring cause there not even close to fitting there way smaller..how much were the 820's i might just do that

 

good Q.
where did you pick up the 860's?

 

where can i find grommets or injectorsto fit the primary KG rail?

 

im using the 750cc injectors from RC engineering found on www.speedmachineperformance.com

 

i just checked them out..do i want the peak/hold 750's or do i want the saturated 750's? whats the differance?

 

KG fuel rails are meant to be use with Bosch top style injectors sorta like the 1600cc injectors you got for the secondaries.

 

I got my 820cc injectors from kgparts.com with the fuel rails. It was like160 shipped for the pair brand new with injector clips.
