BACKFLUSHING THE WATER SEPARATOR
Backflushing is required when dirt and water block the filter element. The following
signs will indicate this:
• Loss of engine power
• Black smoke may exhaust from the engine
• Vacuum gauge will indicate a high restriction reading on the element of the
filter.
1. Stop the engine.
2. Open the bleed screw.
3. Open the drain valve (2).
- The clean fuel above the filter will backflush through the filter element. This
will release the smaller dirt and water particles.
- Drain the fuel until the dirt and water are removed from the filter and the bowl.
4. Close the drain valve (2).
5. Close the bleed screw (DO NOT OVER TIGHTEN).
6. Start the engine.
7. If the engine still lacks power, try backflushing the filter again.
8. If restriction is still too high, change the filter element.
Replacing the filter element of the water separator:
1. Stop the engine.
2. Loosen the lid screws.
3. Remove the lid.
4. Take out the spring cassette.
5. Take out the filter element by the
handle.
6. Replace with new filter element.
7. Re-fit the spring cassette.
8. Check lid gasket is positioned
correctly or replace if necessary.
9. Fit lid checking for correct
positioning, insert screws and
tighten.
