exceed this level, the water may be passed through to the engine and
may cause fuel injection equipment damage.

when draining the DFCM. Fuel may ignite if the separator is
drained while the engine is running or vehicle is moving.
Note:Air will enter into the fuel system if the DFCM is drained while
the system is running. The engine will not operate properly if air enters
the system.
2. Locate the DFCM and place an appropriate container under the drain
