Ok I posted before but I think I wasn't clear. I bought 4 rc injectors 750cc. pl4-750d. They seem to fit in the secondary rail and manifold just fine. I am having a problem with them fitting in the primary holes in the cast. They fit in the rails just fine. When I install them with the rc lower o-rings or even the stock o-rings the body of the injector seems to contact the cast iron housing. they seem to sit a little lower than the stock injector. I know a lot of people run these injectors and from what I have read these are the right injector. Why am I having this issue. I called rc engineering and they told me to install the stock pintle caps on the new injectors which seems impossible. Has anyone had this concern or can antone post a pic of what theres looks like. I will post a couple pics to try and give a better idea. Thanks

They probably want you to install the S5 pintle caps which are bigger than the s4.

I can't believe im the only one that's run in to this one. Have been in contact with tv they say I may need to grind intermediate housing a little. Does this sound right

so you still have your primary air bleeds in the engine?.you need them.
I have been running 4 pl750d's and I had zero problems on install.

Yes still running them. I just took a very small amount of metal off and they fit just fine. we will see when she is back on the road.
