Note: You must drain the secondary fuel filter element (1) before the removal or the replacement of either filter element.

Place a suitable container under the valves (2) and (4). Open the valve (2) in order to drain the upper secondary fuel filter element (1). Immediately open the drain valve (4) after opening the drain valve (2.). This sequence prevents an air lock in the fuel system.

Note: Every new oil filter has rotation index marks that are spaced at 90 degree increments. Use the rotation index marks as a guide for tightening the oil filter.

Slightly loosen the upper secondary fuel filter element (1) by 90 degrees. As the filter is loosened, additional fuel may drain. Loosen the filter by another 90 degrees, and continue loosening the filter in 90 degree increments until no fuel drains from the drain valves.

Close the drain valves (2) and (4).

If the upper secondary fuel filter element is not being replaced, tighten the element. When the gasket contacts the filter base, turn the filter by 270 degrees more. This will tighten the filter sufficiently.

Remove the lower secondary fuel filter element (3). Use caution when you remove the element in order to avoid spilling the fuel that is in the element.

Note: The upper secondary fuel filter element and the lower secondary fuel filter element are different part numbers. Refer to the Operation and Maintenance Manual, "Maintenance Parts List".

Install a new lower secondary filter element. In order to prevent contamination of the fuel system, do not fill the element with fuel before you install the filter element. When the gasket contacts the filter base, turn the filter by 270 degrees more. This will tighten the filter sufficiently.

Prime the fuel system. See the Operation and Maintenance Manual, "Fuel System - Prime".

Start the engine and check for leaks.

Close the access door.
