Fuel Pump
The fuel pump is attached to the frame just outboard of
the fuel injection pump.
The Standard Control Module Run output LED will be il-
luminated when the fuel pump is energized.
Operational Test
1. Park machine on a level surface, lower cutting
decks, stop engine and engage parking brake. Make
sure ignition switch is in the OFF position. Unlatch and
raise hood.
2. Disconnect electrical connector from the fuel stop
solenoid to prevent the engine from firing.
3. Disconnect fuel hose (pump discharge) from the fuel
filter.
4. Make sure fuel hoses attached to the fuel pump are
free of obstructions.
5. Place fuel hose (pump discharge) into a large, grad-
uated cylinder sufficient enough to collect 1 liter (33.8
fluid ounces).
IMPORTANT: When testing the fuel pump, DO NOT
turn ignition switch to START.
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 most Groundsmaster 3500--D machines, the
amount of fuel collected in the graduated cylinder
should be approximately 11.8 fl oz (350 ml) after
thirty (30) seconds.
B. For machines that are equipped with a Biodiesel
Conversion Kit, the amount of fuel collected in the
graduated cylinder should be approximately 16 fl oz
(475 ml) after fifteen (15) seconds.
7. Replace fuel pump as necessary. Install fuel hose to
the fuel filter.
8. Reconnect electrical connector to the fuel stop sole-
noid.
9. Bleed fuel system.
