7. Inspect for holes and tears by looking through the element
toward a bright light. Check for damaged gaskets or dented
metal parts. Do not reuse damaged elements. Protect element
from dust and damage during drying and storage.
8. Reinstall air filter element.
After six cleanings replace air filter. A cleaned filter will have
approximately 70% of the life of a new filter element. A restricted
filter element may not appear excessively dirty.
FUEL FILTERS
WARNING
When working on the fuel system
• Keep naked lights away, do not smoke !
• Do not spill fuel !
-------------------------------------------------------------------------------------
The Vantage is equipped with a Fuel Pre-Filter/Water Separator
Assembly located before the lift pump and a Secondary Fuel
Filter located after the lift pump and before the fuel injectors. The
Fuel Pre-Filter/Water Separator is mounted to the engine block
just below the lift pump. The Secondary Fuel Filter is mounted
directly to the engine just above the oil filter.
FUEL PRE-FILTER/WATER SEPARATOR
ASSEMBLY
The pre-filter is a 150 micron screen designed to protect against
gross fuel contamination of the water separator element and the
Secondary Fuel Filter. If the pre-filter becomes plugged it may be
removed, inspected, cleaned and reinstalled. In general this only
needs to be done with each water separator element change
(about every 1,000 hrs.) However if at any time excessive fuel
contamination is suspected or a sudden fall-off in engine
performance is detected the pre-filter screen should be inspected
and cleaned. Follow the following procedure:
1. Close the fuel shutoff valve (Lever should be perpendicular to
the hose) located on the side of the Fuel Pre-Filter/Water
Separator Assembly.
2. Unscrew the cap ring located on the top of the filter header
and remove the plastic center cap and O-ring.
3. Remove the large white volume plug located directly under the
center cap in the upper cavity of the filter header. Use a small
screwdriver (or similar device) to lift the plug part way out of
the cavity to assist with its removal.
Be careful not to damage the pre-filter screen with the
tool used to remove the plug.
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-
filter 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.
MAINTENANCE
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
header 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 (Lever in line with
the hose) before starting the engine.
WATER SEPARATOR ELEMENT
The water separator element is a two stage filter with a special
filtration/water separating media, and an expanded water
reservoir providing maximum protection against water in the fuel.
The recommended change interval for the water separator
element is 1,000 hours. The procedure for changing the element
is as follows:
1. Close the fuel shutoff valve (Lever should be perpendicular to
the hose) located on the side of the Fuel Pre-Filter/Water
Separator Assembly.
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 further engage the header. With the proper
orientation now established apply additional pressure to seat
the element in the filter header. You should feel the element
"pop" into place when properly seated.
Note: The element will only go on one way. Never use
excessive force when mounting 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 (lever in line with the hose).
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.
SECONDARY FUEL FILTER
The Secondary Fuel Filter is a spin on cartridge type mount
directly to the engine. Consult your engine operation manual for
complete information on service intervals and element changing
procedures.
