Figure 5-21. Fuel Filter
Replace the fuel lter using the following general
procedures:
1. Stop the engine.
2. Put a container under fuel lters before removing
the lter elements.
NOTE: Consider the environment when discarding
used lters and do so according to safe and
lawful practices.
3. Wipe the area around the fuel lter elements and
element mounting heads using a clean, lint-free
cloth. (Figure 5-21)
4. Use a lter removal wrench to loosen and remove
fuel lter elements by turning in a counterclockwise
direction. Drain and discard the removed elements.
5. Wipe the inside area of the lter heads with a clean,
lint-free cloth. Fill the new fuel lter elements
completely with clean fuel.
6. Put clean fuel onto the element rubber gaskets.
7. Install the new fuel lter elements onto the lter
heads. Carefully tighten the elements (by hand
only).
DO NOT overtighten the fuel lter
elements onto the lter heads.
8. Start the engine and check for ANY fuel leaks.
STOP the engine immediately if any
fuel leakage is noted. DO NOT start the engine until
the leakage problem is corrected.
NEVER loosen a fuel injector line as
contents are under high pressure. DO NOT try to
bleed air by loosening injector lines.
Fuel Water Separator
Water and dirt that gets into fuel settles into the water
separator. (Figure 5-22) As it collects, a red oat rises.
When the oat reaches the line on the separator, an
error code will appear on the DP101 digital display. It is
important to drain it immediately.
If you run out of fuel, it is important
to pump the water separator to prime fuel injection
lines. Failure to do so can adversely affect
performance.
To drain the water separator:
1. Pull retainer clip from plug to disconnect the
harness.
2. Unplug the harness, then unscrew the plug.
3. Drain and reinsert components.

2. Loosen and remove the lter body and clean it with
light oil.
