This is a good point about the points on an idle fuel pump. I bought a new
pump for the TD and for the first couple of days it would stop every few
blocks. The old tapping trick would get it going again. Evidently the corrosion
wore off, as the pump has been OK ever since. Relays and switches are usually
designed so the points contact with a wiping motion to keep them clean. Of
course it can't clean itself if its not being used.
