Servicing Water Separator (DPF Models)
The water separator is located between
the fuel tank and the main fuel filter and is
used to remove finely dispersed water in
diesel fuel. Check on a daily basis and
drain if necessary. Water can be drained
from the separator by opening the valve
located at the bottom of the separator
bowl.
Important:
Water in the fuel system can
cause severe engine damage. Drain water
from the water separator anytime water is
present.
To change the water separator filter, turn
the plastic petcock located on top of the water separator a 1/4 turn to stop fuel
flow. Unscrew the separator bowl from the housing and pull down on the existing
filter to release it from the housing. Replace with a new filter and reinstall the
bowl. Return the petcock on the water separator to the open position. Start the
engine and check for leaks.
Servicing Water Separator (Non-DPF Models)
Periodically check for water in water separator by checking level of float in water
separator bowl. If water is present:
1. Shut off the fuel supply by turning the fuel shutoff valve on top of the water
separator.
2.
Turn nut to release the bowl from the valve head. Dispose remaining fuel and
water.
3.
Clean bowl and filter element with warm water until all foreign material is
removed. Replace fuel filter if damaged. Refer to Parts Manual for part num-
ber.
4.
Place element onto valve head. Lubricate o-ring on bowl with diesel fuel and
place on valve head. Turn nut to tighten.
5.
Turn on fuel supply.
Releasing Water from Separator
1. Check red float located in the water separator bowl. If red float is raised, open
valve on the bottom of the bowl to drain water.
