Using the hand pump indicated by the arrows in the illustration, bleed the fuel system. Continue pumping until pumping becomes difficult.

Check the fuel filter warning light.

ПРИМЕЧАНИЕ:

When the fuel filter warning light illuminates and the buzzer sounds, the water in the fuel filter must be drained immediately.

Remove the drain plug and place a small tray to catch the water.

Operate the hand pump until only fuel begins to run out.

After draining, retighten the drain plug.
