I think I misdiagnosed this problem as a turbo problem but now I think it may be fuel starvation. I noticed a lot of debris in the primary (small) fuel filter so I suspect I have crud in the fuel tank that is clogging the in-tank fuel filter. The car starts and runs fine initially, but after driving for several miles at highway speed, the car can't maintain speed going uphill. If I stop there is plenty of power initially but after about mile or so, the car lacks power again. I'll change the secondary fuel filter next (I have a spare) but I want to get the fuel level down lower before I try to drain the tank. And that will take a few days.
Any relevant comments/experience appreciated. Cheers. Scott Ritchey Kittrell NC 1982 300SD 220K 1979 300TD 350K = -------------- next part -------------- A non-text attachment was scrubbed...
