Fuel filter/water separator
The frequency of draining water from the fuel filter/water separator
is determined by the contamination level of the fuel. Inspect or
drain the collection bowl daily.
Replace the element every 500 hours or if high restriction causes
a power loss.
NOTE! Dispose of fuel and contaminants in an environmen-
tally safe manner.
