Thanks to all who gave suggestions = about how to safely get my newly acquired diesel camper running after sitting for 5 = years in my friend's driveway. Here is what I did:

I could not easily get the injectors = or glow plugs off, so I did not add Marvel Mystery oil to the cylinders. I = did however add a quart to the new oil and filled the oil = filter with fresh oil. I pulled the vacuum pump and the oil pressure sending = unit and used a 13mm socket on a drill to spin the shaft of the oil pump until = oil started to come out of the oil pressure sending unit hole. = Replaced the sender and continued to spin the oil pump for a while, until I felt that = oil must have gotten to just about everywhere under pressure.

Added an other quart of Marvel = Mystery oil to the fuel tank and topped it off with fresh diesel. Couldn't figure = out how to drain the old fuel from the tank, so I figured adding as much new = fuel as I could with the additive would help.

A fresh battery installed, and away = I cranked. Two tries at about 10 seconds of cranking and I = remembered the cold start knob. Pulled it out and tried again. Started = right up.

Now I have to mess around with the = brakes a bit, clean out all of the mouse turds in the cabinets, wash the fungus off of = the poptop, and straighten out a little crinkle in the driver's side door, = and I'm off on my first trip. What the heck, the price was right ($1) and = I only wasted 1 1/2 days of non-billable time getting it to run. = :-)
