Has anyone out there installed injectors in a 99-00 civic si, I just got some RC 440's and they just don't seem to seat right in the manifold, the rubber O rings don't fit down in there like the stock ones. Are they supposed to or do they kinda sit a little about it the holes in the manifold so that when you tighten the fuel rail that just get crushed between the lip on the injector and the lip in the intake manifold? This is the 2nd set that I have had that did this. Are there different ones for the Civic Si and the Integra's? Please help my car is ripped apart as I speak

 

my buddy installed a greddy kit on his 00 si and when he put the injectors in, there was a gap between the injector and the manifold. We called greddy and they said that was normal

 

When I installed my dsm 450 injectors, I had to put the o-rings on each injector one by one..if you try to fit all the injectors by simply pushing it into the o-ring, there will be a slight gap. At first I thought i needed thinner rings, soon after I realized that if you jus pull off each o-ring and just place them firmly on each injector one at a time, the fitment should be flush
