Larry D,

I think the diaphragm probably deteriates with age, not mileage. The problem I experienced was mechanical wear, and gave me adequate warning. When it gets to the danger point that Benzmac warned about. You will be hearing a snapping noise from the pump.

Benzmac may tell us that he has seen them go without warning, but I guess I heard the warning, headed it and was lucky.

Good luck,
