I am confused on this one thing. Do you open the water drain valve on the bottom of the filter with the truck running or not? I have tried the big one with it running and nothing really came out. I tried it with the truck off and I could hear air bubbling up into the filter Again, only a dribble of liquid came out what seemed to be clean diesel. I had to prime the truck to get it running again. I think maybe the drain valve is crudded up too. I'm gonna change out all the filters here ASAP.
