4.3 Fuel System Bleeding
Bleed the air from the fuel system to prevent engine
starting failures and/or erratic operation. One or more of
the following causes air to collect in the fuel system:
D
Operating the generator set until the fuel supply is
emptied
D
Air leaking from the suction side of the fuel system
D
Replacing the fuel filter
Note: Connect the battery during the priming procedure
to allow engine cranking.
Do not allow the
engine/generator to start. To prevent starting,
toggle the start/stop switch by momentarily
placing the start/stop switch in the START
position for a few seconds and then placing the
switch in the STOP position.
Procedure to Bleed the Fuel System:
1. Fill the fuel tank.
2. Loosen the fuel filter vent screw. See Figure 4-3.
3. Toggle the start/stop switch until fuel, free of air
bubbles, flows from the vent screw. Tighten the
screw.
4. Loosen the line connection (bleed point) at the fuel
injection pump inlet.
5. Toggle the start/stop switch until fuel, free of air
bubbles, flows from the vent screw at the line
connection on the fuel injection pump inlet. Tighten
the connection.
