BLEEDING THE FUEL SYSTEM
Bleeding air from the fuel system may be required:
1. After the fuel filter has been removed or any fuel lines
have been disconnected.
2. If the fuel tank has been allowed to run dry.
3. After long-term storage.
CAUTION
!
To avoid fire and serious injury, DO NOT bleed
the fuel system while the engine is hot.
IMPORTANT
The air vent on the fuel injection pump must
always be closed during engine operation. The
engine may not run if left open.
PROCEDURE
1. Ensure that there is fuel in the tank.
2. To eliminate air from the fuel filter, turn the air bleed vent on
top of the fuel filter to the [AIR] position. Crank the engine
until the air in the filter is pushed out by the fuel. Do not
crank the engine for more than 10 seconds at one
time. Turn the air bleed vent back to the [ON] position and
start engine. If the engine will not start, proceed to step 3.
3. To bleed air from the injection pump, turn the air vent knob
on the fuel injection pump counterclockwise to open. Crank
the engine for 5 seconds, 3 to 4 times. BE ALERT - the
engine may start during cranking.
