i have a gas leake coming from the fuel rail right above the injector the injector is still working properly i thought maybe it slipped out but it seems to be in good and the clips attaching it to the rail are on good. any idea what the problem is?

 

The O-ring is probably died or cracked. you can get a set of new o-rings for $10 or so.
I would replace all of them...if one is bad, the others are probably not far behind it
