Just last week, I had a similar problem. I had fuel leaking from the drain tube also, mine started after replacing the fuel filter though. My problem was corrected by working the drain valve open and closed a couple of times.

I fixed mine till the black could o rings get here by flipping the stock o rings over drip is no gone competely gone though greatly reduced
When removed you could see 2 indentations in the o rings caused b the valves molding my guess is now that it is colder the rubber has stiffened and isnt sealing as well as normal

Was your leak around the valve as well troubledsol? Mine leak diesel from around the valve and it sits on top of the engine. It is not too bad, and I never saw diesel in the carport. Only reason I saw it is cuz the guys from the tranny shop spotted it and told me about it.

The o-rings are by far the most common leakers. $6 is easily worth it to find out. The filter bowl does not need to be removed to get the seperator valve off, but it is a little tight in there.

Thanks Cookie and kwik. I have been eyebolling this for this past couple of days and it is definitely around the release valve. I already ordered that kit from bcd because I was told these orings are specific. I have boxes of them, but I dont want to risk it. I am suprised that the valve doesnt have a gasket of any type. I think when I put the rings in I will line the valve with permatex to help seal better. Do you think that would be a good idea?

An o-ring properly set in it's little groove makes a better seal than a gasket because it follows the expansion and contraction better IMO. Avoid Permatex and equivelents like the plague. It will glue the o-rings in place and immobilize them from doing what they do best is seal things up even when things are expanding and contracting with the thermal cycles of the engine. Use a VERY light coating of silicone grease on the o-rings so that they can seat properly = no leaks.
