Here is a complete kit to re-seal your 1994-2003 Ford 7.3 Liter Fuel Water Separator/ Petcock.

This Professor Foam kit includes 2 Viton O rings

(either Black or Brown - becouse color is not the way to tell the diferance in the makeup of the o ring)

Since the diesel went to Ultra Low Sulfur many Powerstrokes devloped leakes at the Fuel Water Separator/ Petcock. The reason is the OEM O Rings shrink and were not made for the new fuel variant, but the problem can be easily and cheaply repaired. Professor Foam O rings are made from Viton and they have superior chemical and heat resistance. Check for pooling of diesel in the valley of the motor, and or fluid coming out of the passenger side of the motor, (out of the tube designed to empty the fuel filter canister of the water in the fuel). The good news is that this is a 20 minute fix and will save you over $45.00 from the dealer cost. 

I will include a easy to follow insrtuctions to make this fix an easy thing!
