Here you go

Before you change anything, turn on your key to pressurize the system. Locate the small, yellow-handled fuel filter water drain valve on the firewall side of the fuel filter. Exercise this valve a half dozen times. Maybe you'll get lucky and blow out the cause of the leak. Otherwise:

You need:
1. A #20 Torx driver socket for 1/4 inch drive.
2. A 1/4 inch ratchet
3. From Home Depot's plumbing department, two #90 Danco o-rings. If you don't have a H-D local to you, they're 1/2" od, 1/4" id, 1/8" material, available from most hardware stores.

Optional: Proper size socket and ratchet for removing the "Powerstroke" plastic cover from the top-front of your engine.

For ease, remove the "Powerstroke" cover.
Locate that yellow valve handle at the side closest to the firewall. This is the drain valve. Remember how the pieces are oriented for later re-assembly. Better yet, take a digital picture. There are four #20 Torx screws holding the valve to the filter body. Using the driver socket and ratchet, remove the four screws. Using a toothpick, pry the two little yellow o-rings out of where they fit. Replace them with the two you bought. Lube the threads on the four screws. Re-assemble and check for leaks. Replace the Powerstroke cover.

Just a tip to add to NCHornets post, lay a towel or something down below the drain in the valley. If you drop one of the pieces its a pain to pick em up down there otherwise

Easy but hope you have small fingers.Dont pay for a new valve get the orings when you take it off you will see why you would be if you spent 55 on a new one. I did thats before i found this place good luck.

I went to all of the local hardware stores including Home Depot and couldnt find any orings made of Viton. If you replace with Buna you may be replacing them again in a year.
