Fuel Pump
The fuel pump is attached to the frame just outboard of
the fuel injection pump (Fig. 40).
DANGER
Because dieselfuel is highly flammable, usecau-
tion when handling it. Do not smoke while testing
the fuel pump.Do not test fuel pump while engine
is hot. Make sure that there is adequate ventila-
tion when testing. Always wipe up any spilled
fuel before starting the engine.
Operational Test
1. Disconnect electrical connector from the fuel stop
solenoid to preventthe engine fromfiring (see FuelStop
Solenoid in this section).
2. Disconnect pump fuel discharge hose from the fuel
filter.
3. Make sure fuel hoses attached to the fuel pump are
free of obstructions.
4. Place pump discharge fuel hose into a large, gradu-
ated cylindersufficient enoughto collect 1liter (33.8 fluid
ounces).
IMPORTANT: W hen testing the fuel pump, DO NOT
turn ignition switch to START.
Note: Machines that are equipped with a Biodiesel
Conversion Kit will have the same fuel pump as ma-
chines with serial numbers above 280000000.
5. Collect fuel in the graduated cylinder by turning igni-
tion switch to the RUN position. Allow pump to run for
time listed below, then return switch to OFF.
A. For machines with serial numbers below
270999999, the amount of fuel collected in the grad-
uated cylinder should be approximately 11.8 fl oz
(350 ml) after thirty (30) seconds.
B. For machines with serial numbers above
280000000, the amount of fuel collected in the grad-
uated cylinder should be approximately 16 fl oz (475
ml) after fifteen (15) seconds.
6. Replace fuel pump as necessary. Install fuel hose to
the fuel filter.
7. Wipe up any spilled fuel.
8. Reconnect electrical connector to the fuel stop sole-
noid.
9. Bleed fuel system (see Operator’s Manual).
