I would start by looking at pipes for leaks then unions for tightness. After that get the pump looked at by a Bosch service shop.

Check the flexible pipes for the fuel return that connect between the injectors. These can perish over time and leak, they are also on the unpressurised side of the system so will drip instead of spray.  :wink:
It could be that the fuel is finding it's way into the loom but it has to be coming from somewhere on the unpressurised side, so follow the loom up from the drop and see where it goes.
