bet its yar return lines or the o rings on the leak off caps that go to the injectors. they tend to get dry and hard and then if they get bumped by somthing or someone they leak. starts slow at first then gets real bad or atleast thats what mine did. It took me about 45 minutes to put on all new leak off caps o rings and return lines. just make sure ya get the rite size o rings and ya need 2 for each cylinder. good luck

Check the line from the lift pump up to your fuel filter,it may have rubbed off something causing a small hole or may be leaking at the filter connection and running down the line.

You may also want to check the weep hole in the bottom of the injection pump. It is a real bugger to get to , but you get you finger under the neck of the pump housing right behind the mounting flange. It is important to use an additive to lube the seals in the pump.

When you say the front end is always wet ... where on the front end are you talking about? There is a lift pump ( like gasoline engines ) mounted on the passenger side of the engine that operates off a cam lobe. There is a weep hole on that pump that may be causing the wet spot on the lower front of the engine.
