Engine Maintenance

Draining Water from Fuel Tank
Water run through the system may damage the
injection pump or nozzles. Damage to the fuel
system will subsequently cause more expensive
damage to the engine. A large accumulation of
water in the bottom of the fuel tank will stop a
diesel engine. Water should be drained off during
scheduled maintenance inspections to prevent
breakdowns. Drain the water off after the fuel
tank and unit have remained idle for an hour.
1. Place a container under the fuel tank to catch
the draining water and fuel.
2. Remove the drain plug from the bottom of the
fuel tank.
NOTE: Some fuel tanks have a check valve
in the drain plug fitting. Push the check
valve open with a small screw driver to drain
the tank.
3. Let the water and fuel drain into the container
until no water is visible in the fuel draining
from the tank. If the water and fuel do not
drain freely, the vent may be plugged. If so,
clean or replace the vent.
4. Install the drain plug.
Fuel Filter Replacement
Replace the fuel filter at intervals according to the
Maintenance Inspection Schedule.
1. Remove the filter and discard.
2. Lubricate rubber ring of new filter with fuel.
3. Install the filter and tighten until the filter is
slightly loose (rubber ring not making
contact).
4. Bleed the air from the filter by operating the
electric pump until fuel bubbles appear at the
top of filter.
5. Tighten the filter until the rubber ring makes
contact, then tighten 1/2 turn more.
Electric Fuel Pump
Operation
The electric fuel pump must be mounted next to
the fuel tank. This pump is designed to push rather
than pull fuel.
Make sure the pump completes a good ground
with the battery. The pump will not operate at less
than 9 Vdc. The pump is self priming as long as it
is not higher than 30 in. (762 mm) from the fuel in
the fuel tank.
Maintenance
Field service is limited to cleaning the bottom
cover and filter. The filter and cover gasket are
replaceable.
Disassembly
1. Remove the three screws from the cover.
2. Remove the filter, cover and cover gasket.
Wash the filter in cleaning solvent and blow
out the dirt and cleaning solvent with
compressed air. Check the cover gasket and
replace if damaged. Clean the cover.
