A Series Diesel Engine Lubricating System Flow 121
The bushing (2) in the Bosch VE pump can causes a
seal leak. If the bushing is loose in the housing it will
move toward the seal raising the lip (1) and providing a
leak path for fuel.
To check for such a leak remove the fuel drain
manifold connection (1) at the pump and install a plug
(2).
Remove the access cover and rotate the engine so
one of the holes in the fuel pump gear exposes the
back gear housing.
Activate the fuel shut down valve by turning the switch
to the ON position.
