has any one had a leaky fuel injector in their bird? the #1 injector is leaking, and i replaced the rubber o-rings and i can still see gas dribble out of the top it looks like. my question is does anyone think this could be due to the injector itself and not the brand new o-rings? It almost looks like the gas is comming from under the plastic brown top part of the injector. Anyone had this problem?

Asked and answered. This is the most recent and in depth discussion with good ending. Try search for even more if these do not help.
