F350 Water Separator

[rrheik]

For all of you F350 owners, are you waiting to empty the water separator resevoir when the warning light comes on or are you doing it monthly?

Part of my OIL CHANGE maintenance is to drain the HFCM , never a drop of water in 65K

I ditto what Rod says. open it every oil change and let it run a few seconds to let any water escape. The mechanic tells me he doesn't see any signs of water so I am continuing to buy my fuel from the same places as much as I can.

I also do the same every now and then, but after I had to replace the coil inside and underneath the paper fuel filter from corosion from water I do it more often now.

What was FORD thinking when they designed that system? My old 7.3 was so easy to access, but this one is a pain in the @$$ to get to and then fuel get all over the rail. To answer your question... I have only had the light come on once, removed the plug and drained... no more problems. I have it drained at every oil change.

Thanks, every oil change sounds reasonable. I normally do about 2500 miles between stops for a prolonged period, otherwise I will do it when the warning light comes on. My salesguy who has a ranch and three F350s prettty much says the same. Says he hasn't seen a warning light between oil changes.
