Priming the 6.6L DURAMAX

diesel engine, it has a priming pump which is part of the
engine mounted fuel filter. The vent valve and the
fuel filter primer pump are located on top of the fuel filter
housing. The priming pump is hand operated and is
designed to bring fuel to the engine to eliminate any air
that may be in the fuel lines.

following:
1. Make sure there is fuel in the tank.

properly tightened.
