The truck is new to me so this might be a well known issue. I had a quick search but didn't see any posts for this particular version of the problem. It is a UK spec 1998 2.8TD
There is a small black pipe near the top of the pump that fuel drips out of when I rev the engine. It doesn't happen at tick over, just when I rev the engine. I am guessing it is not meant to be dripping diesel around the engine bay but cannot see any catch pipe that has become disconnected.
The video shows this more clearly than I can explain.
Is there a fault in the pump or is there a missing length of pipe?
