i bought some rc injectors and i cant get the bastards in.....there 550s and going on a h22...they're also going on a venom rail....can someone help me?

 

Probably the same issue as with teh B-series manifolds coupled with RC or other Siemens/Delphi injectors. You have to bore out the inside of the injector grommet and plastic washer to get the injectors to seat properly into the intake manifold.

 

alright i'll try that thanks!!

 

how did you go about boring the o-rings out??

 

Hmm, my RC 310s bolted right into mine.

 

the grommets are too large

Are you using the ones that came with the injectors?

 

I have 550's on my LS/vtec turbo motor. You have to use the factory o-ring to fit correctly. I'm referring to the o-ring that sits on manifold.

 

yeah rc gives you 4, but you still have to bore out the plastic and rubber ones so they fit into the mani

 

I have 550's and they fit fine... Every motor I've built has been fine, send me a picture of what you are talking about and maybee I can better understand what you are talking about.

the injectors dont fit into the mani...when you put the rubber o-rings on the injector they stretch and you cant get the injector in....

LOL On RCs the o-rings don't go on the injectors. They sit on top of them.

 

huh....can you clarify that?

It's clearly stated in the directions that came with mine. They call it a cushion. Some of them have a spacer under the grommet that needs to be removed also.

 

i didnt get instructions.

 

I know what your talking about I have 310's that seemed like they didn't fit what I did was put the injector half way in the o-ring which makes the bottom of the o-ring taper they will then fit into the manifold slightly, then put the fuel rail on a tourque it down they will fit in.

 

i have a after market venom rail...it doesnt put as much pressure on the injectors as the oem does

were you concerned at all about breaking the fuel rail...i'm actually having the same problems and was hoping to get a different sized rubber grommet from RC.

I have put the injectors in and out several times without any problems, just make sure that you only put a little bit of touque on each nut then move on to the next one that will prevent it from breaking. I suppose the proper way would be to go and get the proper grommet though.
