'82 240D, 190k, manual trans.: Had a fuel problem in January. Tank cleaned, strainer replaced, system fully flushed. Very clean fuel now, after two cycles of filters in 1000 miles.

After the last filter change, I bled the engine at the discharge banjo nut on the secondary filter, and it started immediately. However after three days of running errands and then sitting a day, it needs bleeding again.

The book speaks of the engine bleeding itself when running. I presume that's a function of the injector pump. I wonder if a piece of that crud that was in the fuel system got in there and is keeping it from evacuating air from the system.

Any thoughts on this? Can I fix this problem?
