my lly seems to be leaking at injectors 6 & 8 where the fuel lines connect to the injectors. At an idle, I can see the leak which is very small. I have attempted to tighten them but they are already tight as hell. Does anyone know it there is an o ring or some sort of gasket located at these connections that may have gone bad?

Normally the line will just need replaced. I haven't seen the seat on the injector go bad yet... Not saying it can't but haven't seen it yet.

I'll try the cleaning suggestion first but if there is erosion will that be visable and if it does exist, does this mean that the injectors will need replacing? Thanks

Yes, and yes,, But I doubt there will be. Maybe damage if they were misaligned and cranked down but thats not easy to do either. Have the fuel lines been off previously? Or did they just start leaking? Best thing to do is just pull them off, ITs easy enough to do and should be fairly obvious what the problem is..

They just started leaking. I have never removed them. I did have the dealer repair a leak from the fuel rail on the same side but that was over 2 years ago.
I'll just take them off and clean them for starters and if the problem persists I'll go from there. Thanks all for your help.

if cleaning does not work someone might have a used one for the line you need or let me what line it is and I might have the part number laying around.
