are you just using rubber O rings? or HONDA Brown injector seals?

If you just bought regular O rings it will not work they have to be designed to take having gas on them, others will not last,


also when you install them do this..

when the fuel rail is off and the injectors are out and you installed the new rings onto the injectors either spit on the rings, or light oil or WD40 and twist back an forth and stick them into the rail first. then once that is done install the rail back with the injectors in the rail. before you tighten the rail down twist the injectors back an forth again this will make sure they are sealed right. tighten the rail down but not over tighten the nuts. once your done twist the injectors again to make sure they are sealed and your done. Congrats
