Here is a complete Aftermarket kit to re-seal your 1999-2003 Ford 7.3 Liter Fuel Pressure Regulator Water Sensor. 

This Professor Foam kit includes 5 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 filter drain along with the water in fuel sensor and the pressure regulator. 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 Viton and they have superior chemical and heat resistance. 

This Kit consists of:

2 o-rings for the fuel drain kit

2 o-rings for the Water in Fuel sensor

1 oring for the fuel pressure regulator

 All sets will be shipped the next business day after payment.
