Fuel Pump - Toro Reelmaster 5010- H Service Manual

Fuel Pump

The Reelmaster electric fuel pump is attached to the in-
side of the left side frame rail near the fuel tank (Fig. 81).
IMPORTANT: When testing fuel pump, make sure
that pump is not operated without fuel.
Because diesel fuel is flammable, use caution
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 ventilation
when testing. Always wipe up any spilled fuel be-
fore starting the engine.
Fuel Pump Capacity Test
1. Park the machine on a level surface, engage the
parking brake, lower the cutting units and stop the en-
gine. Remove the key from the ignition switch. Raise op-
erator seat and hood.
2. Disconnect wire harness electrical connector from
the engine fuel actuator to prevent the engine from start-
ing (see Fuel Actuator in this section).
3. Disconnect fuel hose (pump discharge) from the
fuel/water separator inlet fitting (Fig. 82).
4. Make sure fuel hoses attached to the fuel pump, fuel
filter and fuel tank suction tube screen are free of ob-
structions.
5. Place disconnected hose into a large, graduated cyl-
inder large enough to collect 1 quart (0.95 liter).
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 ON/PREHEAT position. Allow pump to
run for fifteen (15) seconds, then return ignition switch
to OFF.
7. The amount of fuel collected in the graduated cylin-
der should be approximately 16 fl oz (475 ml) after fif-
teen (15) seconds.
8. Replace fuel pump if testing proves it to be faulty.
9. When testing is complete, install fuel hose to the fuel/
water separator. Make sure to secure fuel hose with
hose clamp.
