    My friend is looking at buying a 1988 (?) F250 with the 6.9 diesel. It gets air in the fuel lines. Is this a common problem? Is it serious? Is it expensive? Are there any other serious problems with this engine?

    You may want to check the fuel return lines for crack.

    Fuel lines are a pretty easy fix in general. I don't know enough about the 6.9 to diagnose though. If it were me I would start at the fuel rails and work my way back.
