I can't imagine coming out with a product (in general any product) that has a high rate of failure from a cause that is going to / has a high probability of happening.

Sorry but if has been shown that constantly running below 1/4 tank does indeed shorten the life span of the pump. Gasoline contains sediment which settles to the bottom. When you go below 1/4 of a tank you have a higher chance of inducing this sediment into the fuel line which will slowly clog the fuel filter over time. The fuel pump thus has to work harder to pump the gas through the clogged filter which shortens the life span. Even so the life span is still pretty long so most people don't worry about it.
