i had a leak a few weaks back, it was dripping out of the fuel drain tube, the orings on the fuel drain releif valve were shot. i replaced the valve (about 50$) and fixed the prob. you can change out just the orings, but make sure you get ones that can handle fuel.
dont know if thats your prob. or not.

You can get just the orings from black cloud diesel performance for about 10 bucks. It cured my leak problem.

I just odrered a bag of the correct o-rings for this application.The o-rings I ordered are made of Viton which has excellent chemical and oil resistance. Temperature range is -15° to +400° F. Durometer hardness is A75. Meets SAE J200.Other guys have used different kinds of rubber but I understand Viton is suppose to be the best for this application. O-ring size 1/2"OD X 1/4"ID X 1/8" thick.The drian valve at the dealer is about $38(includes o-rings), the o-ring kit (4 o-rings) is about $32. When I ordered the o-rings I have, they came in a large quantity.

I have more than I need if you would like to buy a couple of them P.M. me. ($5.00 a pair)

disconnect the drain line (slides off) and remove 4 bolts holding the valve on (torx screws),
