Hey guys, quick question. I just installed a Perrin fuel rail with RC 750cc injectors. My question is I did not install the fat OEM rubber spacer at the top of the injector where it meets the rail. I only have the small o rings installed. It is all bolted down, cannot test it yet, still awaiting a new turbo. The injectors fit snug im just nervous as when I finished I noticed them on the stock injector, im not even sure my new set-up would fit with them on....any help would be appreciated so I dont have to tear it back out to test fit with it on.
