Stop the engine. Connect one end of a hose to each drain valve (2). Insert the other end of the hoses into a suitable container in order to catch the fuel.
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.
Use a suitable container to catch any fuel that might spill. Clean up any spilled fuel immediately.
Remove both vent plugs (3). Open both drain valves (2) in order to drain the secondary fuel filters.Note: If the fuel filter is installed vertically, then the drain valves are in the bottom.
Keep all parts clean from contaminants.Contaminants may cause rapid wear and shortened component life.
Personal injury can result from parts and/or covers under spring pressure.Spring force will be released when covers are removed.Be prepared to hold spring loaded covers as the bolts are loosened.
Note: Some fuel will remain in the housing after the fuel has been drained. This fuel will pour out of the housing when cover (4) is removed. Catch the fuel with a pan. Clean up any spilled fuel with absorbent pillows or towels. DO NOT use absorbent particles to clean up the fuel.
Be alert to the spring force. Gradually loosen but do not remove the last two bolts or nuts that are located at opposite corners of cover (4). Before removing the last two bolts or nuts, pry the cover loose in order to relieve any spring pressure.
