Fuel Pump - Toro Multi Pro 5800 Service Manual

Fuel Pump

The fuel pump is attached to the frame just outboard of
the fuel injection pump (Fig. 40).
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.
Operational Test
1. Disconnect wire harness electrical connector from
the fuel stop solenoid to prevent the engine from starting
(see Fuel Stop Solenoid in this section).
2. Disconnect fuel pump discharge hose from the fuel
filter.
3. Make sure fuel hoses attached to the fuel pump are
free of obstructions.
4. Place fuel pump discharge hose into a large, gradu-
ated cylinder sufficient enough to collect 1 quart (950
ml).
IMPORTANT: When testing the fuel pump, DO NOT
turn ignition switch to START.
5. Collect fuel in the graduated cylinder by turning igni-
tion switch to the ON position. Allow pump to run for fif-
teen (15) seconds, then return switch to OFF.
6. The amount of fuel collected in the graduated cylin-
der should be approximately 16 fl oz (475 ml) after fif-
teen (15) seconds.

nected fuel hose to the fuel filter.
8. Wipe up any spilled fuel.
