Fuel Water SeparatorFuel Water Separator
Water and dirt that gets into fuel settles into the water
separator. (Figure 5-26) An error code will appear on
the PV485 digital display when it needs to be emptied. It
is important to drain it immediately when this occurs.
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.
