Yeah, the black fat O-rings didn't do anything. They seat on the injector real nice, but once in the holder there's nothing to hold down the injector after it's installed. Into my rubber parts box they went.

Because I didn't replace any of the injector parts, except the injector holder O-rings, I expected to have all my vacuum leaks there. I was right, all but three injectors surge when I spray them, I order the RIGHT parts tomorrow.
I just hope I'm not going to need to replace the holders, because that turns a 16$ job into a $80 job, and I don't think there's anything wrong with the holders as they are.
