NOTE
•
If water pump engine runs out of fuel, air can enter the fuel system, interfering with fuel
flow.
This procedure removes air from the fuel system, allowing fuel to reach the injectors
and cylinders.
•
Position suitable drain pan under fitting used to bleed fuel system.
3.
Remove fuel system bleed plug (4) from fuel filter head (5).
CAUTION
Engage starter only for short periods of time (2-3 seconds or less).
Failure to
comply may result in damage to the starter motor or excessive fuel spillage.
4.
With the aid of an assistant hold suitable drain pan under fuel filter head (5) and engage water pump engine
starter to turn fuel pump.
5.
If fuel flows from fuel system bleed port, stop turning engine and install fuel system bleed plug (4) in fuel filter
head (5).
Wipe up any spilled fuel and attempt to start water pump engine (WP 0022).
NOTE
Bleeding the water pump engine fuel system as described in Steps (1) through (5)
normally removes enough air from the fuel system to allow fuel flow and engine start.
If
fuel is not present at fuel filter, there is an air lock elsewhere in the system and Steps (6)
through (11) may be required.
6.
If water pump engine starts, go to Step (12).
If water pump engine does not start, or if fuel does not flow from
fuel system bleed port, install bleed plug (4) in fuel filter head (5), loosen clamp (6), and remove fuel return
hose (7) from fitting (8).
7.
With the aid of an assistant, hold suitable drain pan under fitting (8) and engage water pump engine starter to
turn fuel pump.
8.
If fuel flows from fitting (8), stop turning engine, install fuel return hose (7) on fitting (8) with clamp (6).
Attempt
to start water pump engine (WP 0022).
