Engine Maintenance (Rev 6/98)

To prevent reduced fuel flow to the engine:
1. Trim the 1/4 in. fuel line at a 45° angle.
2. Do not insert the line more than 19 mm (3/4 in.) into
the filter housing.
3. Do not use an internal metal sleeve as it may drift for-
ward, contact the filter housing wall and block fuel
flow.
4. Do not overtighten the compression nut—one or two
turns after contacting the rubber sleeve is sufficient. Do
not tighten the compression nut until it bottoms, or
severe crimping of the line will result.
Water Separator/Fuel Filter
The water separator removes water from the fuel and stores
it. When the stored water reaches the level of the bleed port,
it returns to the fuel tank through the fuel return hose.
Replace the water separator every 3,000 hours.
Replace the fuel filter every 1,500 hours.
If the engine does not come up to full speed or loses speed
under full load conditions, it may be caused by fuel starva-
tion. The fuel line that goes from the outlet fitting on the fil-
ter base to the injection pump may be inserted too far into
the filter base, or the line may be crimped from overtighten-
ing of the compression nut, resulting in reduced fuel flow.
