All of my immediate experience with Hondas are on eg's and ek's and Im just wanting to clarify that for ef's spefically a 91 si, that the injectors have a small o-ring on the top of them to seal into the fuel rail? I just put a mini me into my roomates hatch and he installed the injectors and rail so I never saw everything as it was being installed. when we went to start the car, gas started spewing out of the rail where the injectors meet it.

Someone clarify this, then this topic can disappear (after i see it of course. lol).

 

Yep they have o rings on them

 

yes they should have o rings, I just picked some up from honda for about a buck a peice

 

O rings on the top with little plastic "baskets"
Then the bottom end has one more rubber seal, and below that a rubber "seat"
