7. Start the engine and observe the engine run for a few
minutes. If the engine fails to start, or starts but stops in
a few minutes, repeat the procedure.
Draining Water from Fuel Tank
Water run through the system may damage the injection
pump or nozzles. Damage to the fuel system will subse-
quently 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 drain-
ing 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/Water Separator
The fuel filter/water separator removes water from the fuel
and returns it to the fuel tank.
Fuel Filter/Water Separator Replacement
Replace the fuel filter/water separator at intervals according
to the Maintenance Inspection Schedule.
1. Unscrew the fuel filter/water separator canister with a
strap wrench. Drain, and dispose of properly.
2. Through one of the small openings in the top of the
canister, fill the new fuel filter/water separator canister
with clean fuel. This will purge the air from the canis-
ter. Do not fill canister through the center hole.
3. Clean the filter head seal surface.
