Leaky injector, or lines?
 

Developed a leak around #2 injector. I have tightend the supply and return line as much as I dare, plus loosened and re-tightened them, still seeing dampness in the area. Can the injector itself leak? Or am I more likely to have a line problem?
Truck has 135k on it, injectors are the ones I won on here. They are rebuilts.
