What i found inside my Water Separater.

[08f35]

Have been getting WIF indication since i bought this truck after it sets for 3 or more days. bought a new sensor and gasket for fuel conditioner, opened it up and found a 1/2 inch of sand/grime in bottom. Looks like previous owner which was a Corporate truck had there own tanks they used to fill from.

I nearly fell over when I saw that!!!! holy jeez! I think I'll be tearing into mine sometime soon just for peace of mind

It is an easy task to complete, I would recommend it for the peace of mind for everyone to open it up and look inside. if you have been getting dirty fuel it will sure let you know once you look inside. My WIF sensor was completly buried under what ever that stuff is.
I know the trucks original owner was a underground sprinkler company in Panama city Fl. I suspect they had there own tanks to fill there trucks from.

Any chance you can give a quick write up of the procedure?

u can see inside them pretty good when the drain plug is out

holy sheeeeeet. no wonder our fuel systems are "sensitive"...imagine folks who NEVER drain/clean their separators. So my question is if you drain your OWS monthly and use diesel kleen every fill up, can this still happen?

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.

after seeing how it is made on the inside, i believe if you drain the conditioner into a clear container ATLEAST once a month and looking for evidence of trash in the fuel i think it will prevent it from building it up to my level of contamination.
I am moving next month from alabama to Wa state and will be pulling approx 15000 lbs 4200 miles so i am going through my truck and looking for possible problems. i would rather fix it here then on side of road.
My truck has 105000 miles on and has been a good truck other than a cracked turbo pipe that made it sound like a tea kettle, replaced the original defective radiator at 52000 miles, and then had to replace the engine oil cooler thermostat at 92000 miles.

I have started using diesel clean since finding this and will continue to use it.

As soon as I got my truck I changed both Filters out and have been running Diesel Kleen every fill up. But, this makes me want to tear into mine.
