This is how i went about doing it-
1. I opened Water separater drain and allowed to stop draining ( i have to be less than 1/4 tank of fuel other wise mine keeps going )
2. droped front drive shaft from front axle to allow more room at fuel conditioner.
3. used special tool to unlock and remove the 4 fuel lines from fuel conditioner.
4. disconnect fuel pump and WIF sensor plugs
5. removed the 3 nuts that hold the fuel conditioner assy. on to frame.
6. once assy. removed from frame, removed the 4 star headed bolts that hold the cover on the fuel conditioner, once removed you can see any trash that has collected in the water separator cavity.
mine was so dirty that i removed the fuel pump and filter from the housing and soaked and cleaned the entire fuel conditioner housing. I have changed the fuel filter 3 times since i have had the truck ( bought it with 88000 miles on it ) and i never noticed the build up that had collected on the bottom side of the filter housing, once it was removed and able to look inside it easly the bottom of the filter housing had approx 1/8 inch of same crude stuck to bottom of it.
7. once cleaned and flushed with clean fuel, i put it all back together, with a new rubber gasket and WIF sensor. The WIF Sensor is just pressed in, it takes very little effort to pop it out with a flat tip screw driver or pliers. to reinstall it just press it in with lite tap with a rubber hammer.
The rubber gasket was $30 bucks at ford dealer and the WIF sensor was $28, the gasket should be reusable since it is rubber but i didnt chance it.
