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.

Remove the drain plug from the bottom of the fuel
tank.

If the water and fuel do not drain freely, the
vent may be plugged. If so, clean or replace the
vent.

Install the drain plug.
Fuel Pre-Strainer
The fuel pre-strainer removes the larger contaminant
particles from the fuel before it goes through the fuel
transfer pump and the fuel filter/water separator.
Inspect the fuel pre-strainer during pretrip inspections
and scheduled maintenance inspections. Remove the
bowl and clean the screen if it looks dirty. Fill the bowl
with clean fuel when reinstalling the screen and bowl.
