Fuel Pump - Toro Reelmaster 3100-D Service Manual

Fuel Pump

The fuel pump is attached to the frame just outboard of
the fuel injection pump.
Operational Test
1. Park machine on a level surface, lower cutting units,
stop engine, and engage parking brake.
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.
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
230999999, the amount of fuel collected in the grad-
uated cylinder should be approximately 6.8 fl oz
(200 ml) after thirty (30) seconds.
B. For machines with serial numbers from
240000000 to 270999999, the amount of fuel col-
lected in the graduated cylinder should be approxi-
mately 11.8 fl oz (350 ml) after thirty (30) seconds.
C. 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. Install fuel hose
(pump discharge) to the fuel filter.
8. Reconnect electrical connector to the fuel stop sole-
noid.
9. Prime fuel system.
