Fuel System Air Removal
AIR MUST BE REMOVED FROM THE FUEL SYSTEM.
AIR CAN ENTER THE FUEL SYSTEM WHEN:
1. An engine stopped from lack of fuel.
2. The fuel filter has been replaced or the filter cup has been cleaned.
3. Any connections between the injection pump and fuel tank have been
loosened or disconnected for any reason.
4. The tractor has not been operated for an extended period of time.
5. The fuel pump has not operated correctly.
NOTE:
If the tractor has no fuel, it is possible to put fuel in the tank and
start the engine without doing the air removal procedure, but a small
amount of air can be in the filters. Air in the system will cause loss of
power and stall the engine when a load is applied.
To remove air from the fuel system, turn off the engine and use the
following procedures:
