At least one of the high-pressure pump failures happened
here for the Cessna of our club. It seems that the pump
had been dry some 5 hours before the failure. The Thielert
manual especially warns running the pump dry, and if so
happens, there should be an inspection of the pump
before the next flight.

I'm not sure what you mean, as in "running the pump dry."

Does it require lubricating oil from the engine, which it was not getting,
or "dry" as in the fuel supply was interrupted?
