Priming pump for D5/D7
D5/D7 has no engine mounted priming pump. To be
able to vent the fuel system, if the tank is located be-
low the engine, a prime pump must be installed on a
bulkhead or similar between fuel tank and prefilter.
NOTE! It's important to install the pump with the ar-
row upwards according to the picture below.
