Illustration 4 g00574367 - Clean the outside of the fuel filter assembly. Open the drain on the bottom of the fuel filter. Drain the fuel and the water from the element into a suitable container.
Note: If the element is not equipped with a drain, remove cap (1). Remove the nylon insert in order to reduce the level of fuel in the element. A reduction in the level of fuel in the element will help prevent fuel from being spilled when the element is removed.
Show/hide tableNOTICE 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 the element and rotate locking ring (2) counterclockwise. Remove locking ring (2). 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.
Show/hide tableNOTICE Do not fill fuel filters with fuel before installing them. Contaminated fuel will cause accelerated wear to fuel system parts.
- Ensure that the filter head is clean. Push a new element fully into the filter head.
- Hold the element in place. Fit locking ring (2) into position. Rotate the locking ring clockwise in order to fasten the element to the filter head.
Note: If the nylon insert was removed, install the nylon insert and install cap (1).
- Prime the fuel system. Refer to the Operation and Maintenance Manual, "Fuel System - Prime" for more information.
