My '94 5.9 Cummins developed a leak and following the dribbling diesel fuel took the mobile tech to a Banjo connection on top of the engine that fed the fuel rail, just above the lift pump. Changed that, and all has been well for 87,000 miles. So if you can, try to find and follow the fuel.
BTW, this was back in '04, and they went to low sulfur diesel soon after that. I read lots of forum postings about lift pump leaks but never had one myself...don't think they applied to my mechanic lift pump.
You're correct Jim. It was the electric lift pumps that experienced the problem.
