ADAPTER-DRAIN 1973616 - Caterpillar

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.
Ensure that the engine is stopped before any servicing or repair is performed.
The water separator can be under suction during normal engine operation. Ensure that the drain valve is tightened securely to help prevent air from entering the fuel system.
Place a suitable container under the water separator in order to catch any fluid that might spill. Clean up any spilled fluid.
Ensure that the outer body of the filter assembly is clean and free from dirt.

Typical example
Install a suitable tube onto drain (3). Open the drain valve (2). Rotate the drain valve counterclockwise. Two full turns are required. Loosen vent screw (1). Note: Two complete rotations of the valve will release the valve from the filter element.
Allow the fluid to drain into the container.
Engage the threads of the valve into the filter element and tighten the drain valve by hand pressure only. Tighten vent screw securely.
Remove the tube and remove the container.
