Priming Pump
2. Unscrew the priming pump handle and manually prime the fuel system until air bubbles are
no longer visible in the fuel coming out of the bleed screw.
3. Tighten the bleed screw and screw the priming pump handle back in.
4. Loosen the injection lines at the injection nozzles.
5. Crank the engine until fuel appears at the nozzles.
6. Tighten the injection lines.
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 fuel injection system components. Damage to
the fuel injection 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 during scheduled maintenance inspections to prevent breakdowns. Drain the water 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.

e:: Some fuel tanks have a check valve in the drain plug fitting. Push the check valve open
with a small screwdriver 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.
a.
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 filters the fuel, and removes water from the fuel and returns it to
the fuel tank.
