BLEEDING FUEL SYSTEM Air must be removed : 1) When the fuel filter or lines are removed. 2) When water is drained from fuel filter. 3) When tank is completely empty. 4) When tractor is not used for a long period of time
PROCEDURE OF BLEEDING AIR FROM FUEL SYSTEM
Make sure that fuel Pipe clips are tighten. Open the air vent on the fuel injection Pump.
Pump the fuel pump knob located on the top of the fuel filter. The fuel pump knob will pump easily at first and with added resistance as air is purged from the system. To make sure air is completely purged, pinch the fuel over flow hose with fingers if a pulsation is left when the knob is pumped then, no air remain
(1) Set the hand throttle lever / accelerator at maximum speed position. (2) Turn on the key switch to start the engine and then reset the throttle at the mid speed position. If engine doesn’t start try it several times with 30 seconds Intervals Accelerate the engine to remove the small position of air in the fuel system. If the air still remains and the engine stops, repeat the above steps. Close the air vent.
