ELEMENT REPLACEMENT
Frequency of element replacement is determined by the con-
tamination level of the fuel. Replace the elements every 500
hours, if power loss is noticed or annually, which ever comes
first.
1. Switch off the engine.
2. Fuel supply from the fuel tank may need to be blocked
to prevent fuel flow from the tank.
3. Wipe the area around the filter to clean any dirt from the
area.
4. Remove the T-handle and lid.
5. Remove the element by holding the bail handles and
slowly pulling upward with a twisting motion. Dispose
of properly.
6. Replace old lid gasket and T-handle O-ring with new
seals (supplied with new element). Lubricate both seals
with motor oil or diesel fuel before installation.
7. Refer to Priming of auxiliary fuel filter or fill the unit with
clean fuel, then replace the lid and T-handle then
tighten snugly by hand only.
NOTE: Do not use any tool for removal and installation of T-han-
dle.
PRIMING OF AUXILIARY FUEL FILTER
1. Remove the T-handle and lid from the top of the filter
assembly.
2. Fill the filter assembly with clean fuel.
3. Lubricate lid gasket and T-handle O-ring with clean fuel
or motor oil.
4. Replace the lid and T-handle and tighten snugly by hand
only.
NOTE: Do not use any tool for removal and installation of T-han-
dle.
5. Start engine and check for fuel system leaks.
6. Correct as necessary with engine off and pressure

DRAINING WATER
Frequency of water draining is determined by the contamina-
tion level of the fuel. Inspect or drain the collection bowl of
water daily or as necessary. The collection bowl must be
drained before contaminants reach the top of the turbine or
when the Water Detection Module (optional) indicates it's
time to drain water.
PRESSURE APPLICATIONS / INSTALLATIONS:
1. Open the self-venting drain plug on the bottom of the
bowl to evacuate water and contaminants with a sui
able collection container in place. Head pressure will
push any water and contaminants out of the drain while
keeping the filter primed.
2. Close the drain after all the water and contaminants
have been evacuated.
3. If necessary, follow priming of auxiliary fuel filter.
NOTE: Do not leave the drain open too long as it may completely
drain the entire filter assembly of water and fuel.
