I'm with 8tsixt on the drain valve on the fuel separator. You might try opening it and then closing it again. That helped me get by until I had a chance to replace the o-rings.
Get viton over buna o-rings, they'll last a lot longer. The size is: w1/8" x inside dia. 1/4" x outside dia 1/2"
Springer Pop put up a good link to common 7.3L o-rings and such found here:

You can buy the whole valve from Ford if you want part# F81Z9A153AA, runs about $50.
Thats what I ended up doing as I was on the road when I needed it. Then I got the O-rings from a plumming parts supplier. Now when it happens again I'll just swap out the valve.
Good Luck,
Austin

It's straight forward. You'll need a torx bit or screwdriver for the screws. I can't remember if it's a T10 or T15. I think a T10. Just drain the fuel separator then remove and replace the valve. Nothing to it.
Good luck,
