FUEL FILTER
See Figure 29.
All models have an in-line fuel filter/strainer, only the
24.5 HP Diesel Model has an electronic signal generated
from the filter/strainer. This specific filter/strainer has a
fuel-water separator. When the water fills to a certain
level, an indicator lamp on the instrument panel will illu-
minate to alert the operator to drain the water accumula-
tor.
Refer to the engine manufacturer’s manual for specific
information regarding engine component testing and
replacement.
FUEL PUMP/FUEL SOLENOID
Air-cooled engine models have a vacuum-operated fuel
pump which is part of the engine. Liquid-cooled engine
models have an electronic type of high pressure fuel
pump or solenoid, which is different for each model,
based on the engine manufacturer. Therefore, it is
extremely important to refer to the tractor's specific
engine manufacturer’s instructions for service, repair,
and replacement parts.
NOTE: Before beginning any work on the fuel pump or
fuel solenoid, disconnect and secure the negative battery
cable.
