I bought a used set of RC 550cc injectors from a guy on hear about a month ago and when I went to install them today I realized they don't fit very snugly in the intake manifold. The top where it goes into the fuel rail is fine but it's not a nice tight fit in the intake manifold like the stock ones are. The part number is PL9-550 and a google search says they fit:

92-95 Honda Prelude OBD1 (H22a, H23)
90-95 Honda Accord OBD1 (F22a, F22b)

Am I screwed or can I make these work somehow?

Did you tighten down the fuel rail? They should be snug against the rubber o-ring in the manifold once you tighten the rail.

 

I was just messing with it a bit more and it doesn't fit down far enough into the manifold for the fuel rail to be tightened down all the way. I don't want to force it down and screw things up more either.

 

I just found this:

apparently they are supposed to come with new rubber piece for where they sit in the intake manifold. I have no idea where to get just those pieces.

 

here is a thread I made a while ago that might help you out

I'll check it out now but I think I figured it out. I emailed RC and they sell the "cushion" for $2.50 a piece.

 

So I called today to order the lower manifold seals and the guy told me they are the same as the stock ones but there is supposed to be a plastic piece under the seal that remove and then you reinstall them. Well I have no such plastic piece and when I tried to tighten the rail down on the stock lower seals is started to compress the crap out of the rubber piece that sits on top of the injector. I've seem some guys run a spacer on the studs where the rail bolts up to the manifold and some guys talk about dremeling out the stock seals. Does it matter which way you do it?

 

if it helps, I ran spacers on the connection between the rail and the manifold I have pics if it will help

 

I've heard of people doing that. I just figure there is a certain gap that needs to be maintained in order for the fuel to atomize correctly. It seems that putting spacers on the studs is the way most people do it...

 

everything sounds fine to me. you have the instructions from RC so i would follow them. if you are worried about the upper cusions getting smashed then get a spacer but i think you should just torque everything to spec and call it a day

 

I'll figure something out...
