How moist? The fuel water separator switch on the fuel filter can develop a leak. It leaks down the front of the engine block then onto the ground and that can affect your fuel mileage. Before you buy the "O" ring kit, open and shut the valve a few times to make sure a bit of dirt isn't in there causing the valve to leak. One of the members here sells a kit that takes care of that problem for under ten bucks.
Diesel Kleen is Power Service. Thats what the big PS stands for on the bottle. Good stuff. You need to put in the bottle that says "injector cleaner" and it recomends 1 gallon to 100 gallons fuel. I dump 1/2 gal and then fuel up.then when I use more than 10 gallons diesel, I dump the other 1/2 gal and fuel up again. Takes me from black smoke and injector knock to running clean and smooth.
