WARNING
The fuel pump high-pressure fuel lines and fuel rail
contain very high-pressure fuel. Never loosen any
fittings while the engine is running. Personal injury
and property damage can result.
After Filter Change:
Primary Method:
Unlock the manual priming pump handle by turning
counterclockwise. Pump the primer handle until resistance
is felt (approximately 140-150 strokes). Lock the manual
priming pump handle and crank the engine. Start should
occur within 5 seconds.
NOTE: Do not fill new filters with fuel prior to assembly as
this will allow unfiltered fuel to enter the system and may
cause damage to fuel system components.
Alternative method:
Unlock the manual priming pump handle by turning
counterclockwise. Pump the primer handle 60 times. Lock
manual priming pump handle and crank the engine. Start
should occur within approximately 20 seconds.
NOTE: Do not exceed starter cranking limitations.
After Running the Vehicle Tank Dry:
Ensure there is fuel in the vehicle fuel tank. Unlock the
manual priming pump handle by turning it
counterclockwise. Pump the primer until resistance is felt
(50-60) strokes. Lock manual priming pump handle and
crank the engine. Start should occur within 5 seconds.
NOTE: Do not remove and fill filters with fuel prior to
priming the system in an attempt to reduce priming time
as this will allow unfiltered fuel to enter the system and
may cause damage to fuel system components.
NOTE: It is not necessary to vent air from the high-
pressure fuel system before starting the engine. Cranking
the engine will prime the fuel system.
