MAINTENANCE

4. Using a pair of pliers, gently tug on the pull tabs of the pre-filter

screen in an alternating pattern to gradually remove the pre-fil-
ter screen.

5. Brush off any debris and rinse in diesel fuel.

6. Re-install the pre-filter screen into the upper cavity of the filter

header making sure the four pull tabs are pointing up. Putting
your fingers on the pull tabs, push down evenly until the lower
body of the pre-filter screen contacts the floor of the upper
cavity.

7. Re-insert the large white volume plug into the upper cavity.

8. Place the O-ring onto the angled seal surface of the filter head-

er and re-install the plastic cap. Make sure its flange rests on
the O-ring.

9. Screw on the cap ring and tighten hand tight.

10. Remember to open the fuel shutoff valve before starting the

engine.

WATER SEPARATOR ELEMENT

(For codes below 11409)

The water separator element is a two stage filter with a special fil-
tration/water separating media, and an expanded water reservoir
providing maximum protection against water in the fuel. The rec-
ommended change interval for the water separator element is
1,000 hours. The procedure for changing the element is as fol-
lows:

1. Close the fuel shutoff valve located under the fuel tank.

2. Rotate the quick change ring (located just below filter header)

clockwise approximately 1/2 turn and slide it down and off of
the element.

3. Grasp the element and pull down with a slight rocking motion

to remove the element from the grommet post on the bottom of
the filter header.

4. Slide the new element onto the grommet post on the bottom of

the filter header until the element no longer easily moves up into
the filter header. Now rotate the element (may take almost 1 full
turn) with a slight upward pressure until the element begins to fur-
ther engage the header. With the proper orientation now estab-
lished apply additional pressure to seat the element in the filter
header. You should feel the element “pop” into place when prop-
erly seated.

Note: The element will only go on one way. Never use excessive
force when mounting the element to the header.

5. Slide the quick change ring up over the element and rotate counter

clockwise until an audible  click or  pop is heard. If you do not hear
the click you have not rotated the ring far enough and  the element
is not in the locked  position. Another indication that the ring is in
the locked position  is that one set (it doesn’t matter which one) of
arrows located on the outside of the ring should be located directly
under the air vent valve.

6. Open the fuel shutoff valve.

7. Open the air vent valve on the front of the filter header until fuel

emerges free of air bubbles and then close the air vent valve.

Note : Consult your engine operation manual for information on air
bleeding the entire fuel system

FUEL PRE-FILTER/WATER SEPARATOR ASSEMBLY

(For codes 11409 and above)

The assembly uses a 30 micron pre-filter/water separator element
that is designed to protect against gross contamination of the final
fuel filter. Using chemically treated paper media the element also pro-
vides maximum protection against water in the fuel. The assembly is
also equipped with a see-through bowl for easy visual checking for
water. The recommended change interval for the pre-filter/water
separator element is 1,000 hours. See below for information on the
see-through bowl and for the procedure for changing the element.

See-Through Bowl:

• Check the see-through bowl for water regularly. Water will collect

at the bottom of the bowl and appears different from the fuel.

Note:

The see-through bowl is re-usable.

1. Close the fuel shut-off valve.

2. Drain by opening the self venting drain valve and allowing all water

to escape.

3. Close the drain valve and open the fuel shut-off valve.

Pre-Filter/Water Separator Element:

1. Close the fuel shutoff valve located under the fuel tank.

2. Rotate the quick change ring (located just below filterheader)
