AIR BLEED PROCEDURE
NOTE: A certain amount of air becomes trapped in the fuel system when fuel system components are serviced or replaced. Bleed the system after
fuel system service according to the following procedures.
WARNING: Do not bleed air from the fuel system of a hot engine. Do not allow fuel to spray onto the exhaust manifold when bleeding air from the
fuel system.
MANUAL BLEEDING
Some air enters the fuel system when the filters or injection pump supply line are changed. This small amount of air is vented automatically from the
injection pump through the fuel drain manifold. This is if the filter was changed according to instructions.
