Fuel Pump - Toro Reelmaster 5210 Service Manual

Fuel Pump

The Reelmaster fuel pump is attached to the inside of
the left side frame rail near the fuel tank (Fig. 65).
IMPORTANT: When testing fuel pump, make sure
that pump is not operated without fuel.
DANGER
Because diesel fuel is highly flammable, use cau-
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.
Fuel Pump Capacity Test
1. Park machine on a level surface, lower cutting units,
stop engine and engage parking brake. Remove key
from ignition switch. Raise operator seat and hood.
2. Disconnect harness electrical connector from the
engine fuel stop solenoid to prevent the engine from
starting (see Fuel Stop Solenoid in this section).
3. Disconnect fuel hose (pump discharge) from the
fuel/water separator inlet fitting (Fig. 66).
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 sufficient enough to collect 1 quart (0.95 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 if necessary. Install fuel hose to
the fuel/water separator. Make sure to secure fuel hose
with hose clamp.
8. Connect harness electrical connector to the engine
fuel stop solenoid.
9. Bleed the fuel system.
10.Lower and secure operator seat and hood.
