1996 Dodge Truck 6 cyl Four Wheel Drive Automatic 125000 miles

I am working on a 1996 Dodge 3500 with the cummins diesel in it, and in the last month or so it has been loose prime in the fuel system. If the truck sets for more than a half a day you have to use the manual fuel prime pump on the drive side of the motor. Do you have any suggestions, there are no visable leaks from any of the fuel lines or injectors. Thanks for the help.

Sounds like it loosing pressure by leaking injectors or a bad fuel pressure regulator, it could even be caused by a faulty pressure test port valve.
