Diesel fuel in the valley, and I suspect the drain valve assembly "o" ring has gone bad. Rebuilt with a complete fuel bowl seal kit ( from Clay ) 14,000 miles ago.
Am thinking to only replace tho "o" rings in the drain valve assembly $6.15 from Clay.
Searched this forum and could not find a How To link for tools needed, steps, etc.
Any suggestions and help will be appreciated.
2000 7.3;170,000 mi.;or maybe a Denver area forum brother as my mechanic friend is laid up with a knee replacement.

 

Video's on Utube I'm sure..

 

Here is one of the video by DieselTechRon (RIP)


Also DieselORings has better set of o rings

Hope this helps.

I'd try flipping the valve back and forth to see if it might stop and confirm that it is the cause of the leak before I worked on it.

 

Thank you all for your help.
