Fuel system air bleed
NOTICE: When the fuel tank has been emptied after re-
placement and/or draining water of the pre-fuel filter or the
fuel filter (4) has been carried out, be sure to bleed air as
this may prevent fuel flow because of air entering inside.

hose.
2. Set each cock of (A), (B) and (C) as follows.
Cock (A) (fuel tank): Open
Cock (B) (engine): Close

3. Loosen the air bleeding plug (2) on fuel filter. Do not
loosen the air bleeding plug of the pre fuel filter.

the "On" position. Electromagnet feed pump operates
by this.
ATTENTION: Do not turn "On" the ignition key for
more than 5 minutes unless bleeding air has been
completed. Otherwise, this may cause breakdown of
the electromagnetic fuel pump.
