im replacing my stock fuel injectors on my gsr integra right now ( in the middle of installing a turbo ) and when i go to stick my RC 550 injectors they dont seem to fit like the OEM ones did .... how do these go in? do i take the rubber seal out or does the fuel rail hold them in there??

 

You remove the OEM lower seals and use the new ones that came with the injectors.

 

i bought mine used..didnt come with the seal..where can i get them?

 

Well, the RC seals are about half the height of the OEM ones, so maybe you can get them out of a universal seal kit at the auto parts store.
