Kubota Diesel Engine
Prime Fuel System
IMPORTANT: The fuel system must be primed when
a new engine is started for the first time, if it runs out
of fuel, or if maintenance is performed on the fuel
system.
Note: The fuel pump, located on left side of engine,
under the fuel injection pump and behind the fuel stop
solenoid. It can be manually primed to get fuel from fuel
tank to fuel filter/water separator (Fig. 7).
1. Park machine on a level surface. Stop engine. Re-
move key from the ignition switch.
2. Raise engine cover.
3. Insert a 3/16–inch hose over the bleed screw, and
run the other end of the hose into a container to catch the
fuel (Fig. 8).
IMPORTANT: Priming fuel filter without opening
bleed screw may damage priming plunger.
4. Loosen fuel filter/water separator bleed screw a few
turns. Pump priming plunger until a steady stream of fuel
comes out of hole in in bleed screw. When fuel stops
foaming, tighten the bleed screw during the down-
stroke of the priming plunger. Wipe up any spilled fuel
(Fig. 8).
Note: It may be necessary to bleed the air out of the
fuel line between the fuel filter / water separator and the
injection pump. To do this, loosen the knob on the injec-
tion pump (Fig. 7) and repeat bleeding procedure.
5. Pump priming plunger until resistance is felt. Try to
start engine. If engine does not start repeat step 4.
