fuel separator drain ball valve leaks

[FixitMan]

The drain ball valve (plastic) on the fuel separator filter leaked through the top at the handle. Instead of spending the $71 at ford for the cheezy little valve, I pulled it apart, cleaned it and replaced the 7mm o-ring on the shaft. Thought I would pass the info along. Easy fix.

only problem with this repair is that you have to be very carefull with what o rings you use.......some o rings will deteriorate in diesel fuel...

In case anyone runs into this problem again, I had a minor issue with leaking fuel a while back, thinking it was the orings on the drain valve I called around and International had the entire drain valve assembly for $15.97 for the 7.3. I thought that was pretty cheap.

how do you change fuel valve on 7.3 diesel

As I recall, 4 small star drive screws on back of fuel separator removes it. Take the handle off, the shaft will come out when rotated to the correct key position. There will be a small o-ring on the shaft that has gone flat. I used one from a hydraulic o-ring kit I have at work. Don't use one for plumbing as it wont last with fuel. One of the guys I work with just had the same problem last week. We are now getting fast at self repair. I keep a spare in the glove box now. I see you can get one from International cheap now, ford charges too much. Wouldn't hurt to get a new one from International if you have a parts house close & fix the old one for a spare...good luck!
