Leak on our in hp fuel pump

[RayB]

I have diesel oil that is driping from the hp fuel pump. I can't see where it is coming from, has anyone else had this happen. Do the pumps leak around the bodys. The truck runs and starts just fine. Where should I start looking

the cp3 doesnt use oil in it so would have to be the seal between the front cover and pump itself. as long as you are talking common rail...
