All high pressure fuel pumps will eventually fail. The question with the different types of pumps is how soon and what other parts will they take along with them when they do. Some pumps are more sensitive to contamination and overheating while others are not so sensitive. Some pumps mostly just loose pressure when they fail not causing damage to other components while others grenade taking out the whole fuel system with it. There are steps one can take to prolong the life of a pump, but the bottom line is that it will eventually fail.
