Make sure that the engine is in operating mode.

Open the bleed nipple (1) on the fuel filter. Press the primer
pump (2), until fuel free from bubbles of air starts to flow out.
Continue to pump 15-20 strokes. Check that there is no fuel
leakage.
Note: In cases where the engine is equipped with fuel shut-
off valve, it is often necessary to bleed on the injection pump
as well. This is done by opening the pressure equalizer (3)
(27 mm U-key). Pump manually until fuel free from air bub-
bles flows out.
