Fuel Pump
The fuel pump is attached to the main frame rail behind
the front panel under the operator seat (Fig. 38).
The Standard Control Module Run output LED will be il-
luminated when the fuel pump is energized.
Operational Test
1. Parkmachineonalevelsurface, lower cutting deck
(or implement), stop engine and engage parking brake.
Make sure ignition switch is in the OFF position. Unlatch
and raise operator seat to gain access to fuel pump.
2. Disconnect electrical connector from the engine fuel
stop solenoid to prevent the engine from starting.
3. Disconnect fuel hose (pump discharge) from the inlet
fitting on the fuel/water separator (Fig. 39).
4. Make sure fuel hoses attached to the fuel pump are
free of obstructions.
5. Place disconnected fuel hose (pump discharge) into
a large, graduated cylinder sufficient enough to collect
32 fluid ounces (0.9 liter).
IMPORTANT: When 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.
6. 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
280000000, 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.
7. Replace fuel pump as necessary. Connect fuel hose
to the fuel filter.
8. Connect wire harness electrical connector to the fuel
stop solenoid.
9. Bleed fuel system.
1. Fuel hose (discharge)
2. Hose clamp
3. Fuel pump
4. Screw (2 used)
5. Fuel hose
6. Fuel filter (if equipped)
