Bleeding Air in Low Pressure Fuel Circuit
1.

Press the priming pump (A) about 50 times.

2.

Open the air bleeding hall after removing the bolt (B) for bleeding using a screwdriver.

3.

After install the screw, press the priming pump (A) again about 15 times.

4.

Open the air bleeding hall after removing the bolt (B) for bleeding using a screwdriver.

5.

After install the screw, press the priming pump (A) again about 5 times.

note

The number of pressing the priming pump is an estimated number.

If you work this procedure actually, you should press the priming pump until it gets stiff.

After removing or replacing the part below, bleed air in low pressure fuel circuit.

-

Fuel Tank

-

Fuel Sender

-

Fuel Filter

-

High Pressure Fuel Pump

-

Low Pressure Fuel Lines

caution

If you try bleeding air just once, air is not bleeded perfectly.You should try bleeding air over 2 times.

Draining Water from the Fuel Filter

The fuel filter for diesel enging plays and important role of separating water from fuel and accumulating the water in its bottom. If water accumulates in the fuel filter, the warning light comes on when the ignition switch is in the ON position.

caution

If the water accumulated in the fuel filter is not drained at proper times, damages to the major parts such as the fuel system can be caused by water permeation in the fuel filter.

6.

Place a water trap under the fuel filter.

7.

Remove the air cleaner assembly.
