Typical example
The fuel injection pump is equipped with manual fuel
priming pump. The manual fuel priming pump handle
(1) is on the fuel injection pump above the fuel
transfer pump. With the manual fuel priming pump
handle, fuel can be pumped from the tank through
the fuel filter when the engine is stopped. The
quantity delivered on each stroke of the plunger is
approximately 0.6 cc (0.03661 cubic inch).
Note:
The length (A) of the stroke of the fuel priming
pump handle is approximately 25 mm (1 inch).
Use the following procedure to remove air from the
fuel system:

Typical example
1.
Unlock the fuel priming pump handle (1). Turn
handle counter clockwise. Pull the fuel priming
pump handle upwards.
2.
Loosen the vent screw (3) on the fuel filter.
3.
Push down and pull up the fuel priming pump
handle for approximately 30 seconds.
4.
Continue to operate the fuel pump handle until
strong pressure can be felt, or until fuel free from
air can be seen coming out of the fuel filter vent
screw (3).
5.
Press in the fuel pump handle and lock the handle
into the fuel pump body. To lock the handle, turn
handle clockwise. Tighten fuel filter vent screw to a
torque of 1.5 N·m (13 lb in).
Note:
The stronger the pressure in the fuel system
the quicker the engine will start.
NOTICE
Do not crank the engine continuously for more than
30 seconds. Allow the starting motor to cool for two
minutes before cranking the engine again.
6.
Wait 30 seconds and start the engine. This
procedure will remove any air that could be
trapped within the fuel system. Check for leaks in
the fuel system.
Refer to Operation and Maintenance Manual,
“Starting the Engine” for more information.
