New Aftermarket Viton Fuel Filter Drain & Valve Stem O-rings for

1999-2003 7.3 diesel Powerstroke Ford

4  Drain Valve O-rings 

2  Valve Stem O-ring

If you're smelling fuel, seeing fuel drip from the back or from the separator drain tube on the passenger side of your Powerstroke, or have a puddle growing in the valley on top, there's a good chance that this is the problem. Seems that the newly mandated ULSD (ultra-low-sulphur-diesel) likes to shrink these o rings...

The factory o-rings are Buna-Nitrile. Replace them with our Viton O-Rings. Viton will hold up to Bio-Diesel and ULSD. 

This kit contains 6 black or brown viton O-rings - color has nothing to do with what its made of, Viton is stronger and more resistant to chemicals. Someone who is selling o rings that are brown and calling them viton is mistaken, any type of o ring can be sold in any color, so color is not a trade of Viton!
