Fuel leaked or spilled onto hot surfaces or electrical components can cause a fire. To help prevent possible injury, turn the start switch off when changing fuel filters or water separator elements. Clean up fuel spills immediately.
Do not allow dirt to enter the fuel system. Thoroughly clean the area around a fuel system component that will be disconnected. Fit a suitable cover over disconnected fuel system component.
Turn the fuel supply valve to the OFF position before performing this maintenance. Place a tray under the fuel filter in order to catch any fuel that might spill. Clean up any spilled fuel immediately.

(5) Drain valve for fuel filter
Close the fuel supply valve.
Clean the outside of the fuel filter assembly. Open drain valve (5) and drain the fuel and water from fuel filter (4) into a suitable container. Note: If the fuel filter element is not equipped with a drain, remove cap (1). Remove the nylon insert in order to reduce the level of fuel in the fuel filter element. A reduction in the level of fuel in the fuel filter element will help prevent fuel from being spilled when the element is removed.
Do not use a tool in order to remove the fuel filter. Attempting to remove the fuel filter with a filter wrench or a filter strap could damage the locking ring.
Hold fuel filter (4) and rotate quick release collar (3) counterclockwise. Remove quick release collar (3). The used element should be removed and discarded. Note: If the element is equipped with a sediment bowl, remove the sediment bowl from the element. Thoroughly clean the sediment bowl. Inspect the O-ring seals. Install new O-ring seals, if necessary. Install the sediment bowl to the new element. Hand tighten the sediment bowl. Hand tightening is the only method that should be used.
Do not fill fuel filters with fuel before installing them. Contaminated fuel will cause accelerated wear to fuel system parts.
Ensure that the fuel filter base is clean. Push a new fuel filter fully into the fuel filter base.
Hold the fuel filter in place. Fit locking ring (3) into position. Rotate the locking ring clockwise in order to fasten the fuel filter to the fuel filter base. Note: If the nylon insert was removed, install the nylon insert and install cap (1).
Prime the fuel system. Refer to Operation and Maintenance Manual, "Fuel System - Prime".
