i know it should be an easy task but somehow i found a way to foul that up...

I have a HUMONGOUS vacuum leak and after spraying carb cleaner i have found that all 4 of my injectors are not seated properly.

the question is, how many, or what kind of seals are between:
a) manifold & injector
b) injector & fuel rail

what i think is between A, there's a rubber seal about 1/2 CM thick and pretty wide. between B, there's a small rubber ring around the top, tip of the injector which secures it snuggly into the fuel rail. all of these seals came with the RC550 injectors that i ordered.

i installed them by

1) sticking them into the fuel rail
2) with all 4 injectors on the rail, i inserted the whole unit into the intake manifold
3) tighten the 3 nuts that hold the rail down.

i've heard that some people put two seals between A. is that ok? what should i do to stop the leak? this is for a 2000 prelude.

thanks a lot!!!

 

There are a lot of different sizes of O-rings depending on application. You probably just have the wrong ones. Safe thing to do is to pull the O-rings off your old injectors and put them on the new injectors.

 

i'll try that
