spillage immediately. Material used to contain spillage must be disposed of in
an approved receptacle.
Before servicing any part of the fuel system:
• Stop engine and disconnect the battery.
• Drain the fuel system completely.
• Perform fuel system service in a well‑ventilated area.
• Inspect any completed service work for sign of fuel leakage.
FUEL LINE INSPECTION
Visually inspect the fuel line and primer bulb for cracks, swelling, leaks,
hardness, or other signs of deterioration or damage. If any of these conditions
are found, the fuel line or primer bulb must be replaced.
WATER SEPARATING FUEL FILTER
This filter removes moisture and debris from the fuel. If the filter becomes filled
with water, the water can be removed. If the filter becomes plugged with debris,
replace the filter. The warning system engages when water in the fuel filter
reaches the full level. Refer to Warning System in Features and Controls.
Refer to the Inspection and Maintenance Schedule for the proper
maintenance interval.
