this is how they seat in the manifold with the plastic washers under the rail


...and this is how it looks without the washers under the fuel rail,Im not sure what to do...can somebody help me out?

 

Install everything as it was with the original injectors. Missing pieces will make the manifold leak, and your engine idle like crap.

 

the first picture is how everthing was originally....am i not supposed to use the 3 plastic washers under the rail with the RC injectors?

 

stick the injectors into the manifold first and then put the rail on top. Make sure your lube up the top o-rings otherwise they will rip. The injectors are probably to far into the fuel rail.

Um...no.

OP: The injectors should be a compression fit between the rail and the manifold. Are you using an aftermarket rail that's not supposed to have spacers installed between it and the rail?

 

ok..its impossible for the injectors to be seated to far in the rail,Im using the stock fuel rail,and ive tried to put the injectors on first....nothing is working!!!! Can i just take the rubber washers off?

 

I can't see the pics at work, but I can gather you're doing an RC injector install on a stock fuel rail. I had similar issues installing the 440's on my stock D16 fuel system, but ended up using all the original parts to get them installed. They felt a bit more snug than usual.

I'll take a look when I get home and see if you're running into the same problems.

dont use the washers under the rail then.

 

Just took a look at the pics - obviously, with the washers installed is not the way to go.

How snug do they fit w/o the washers? If pretty snug, then I'd install them that way. If they're too loose, you've got some other issues. If too tight, you can always back it off with regular thin machine washers.

Do you have the O-rings that came with the RC injectors?? The ones that are between the injectors and the manifold?? If not, you should order them from RC. They are reasonably priced and they get em out quick. The injectors are usually really snug and sometimes hard to get into the fuel rail. But, I would "ASSUME" and thats all I would do because I am no expert, I would say its not the fuel rail but the orings for the manifold. Just an assumption.

 

I have the washers that sit between the injector &rail and the o-rings from the kit installed.I just removed the spacers between the rail & manifold and they sit snug now.

 

What size injectors are those? I've have problems with 440's fitting in the manifold the way they should.

 

550's

 

Those rail spacers are only need for some single cam applications. If you're running the RC's on a B series, you don't need them. Just install them like usual using the new lower seals provided by RC.

 

Um...I have a B16 and my 550's fit fine. You seat the O-rings into the manifold first, then you fit the injectors into the fuel rail. Then you fit all the injectors attached to the fuel rail into the o-rings (manifold) and then tighten down the fuel rail in steps with the 3 nuts (10mm head) to about 104 in-lbs or 8.5-9.0 ft-lbs. Use the 3 spacers and everything should work fine. I even use OEM style o-ring sets, but I just lube everything up with motor oil. I just did this the other day to switch everything out for emissions.
