Oldsmobile/Buick Repair: sputtering in a 2000 alero, fuel pumps, fuel filter

Question
would sputtering be a fuel pump or fuel filter problem. my car seems to be sputtreing stalling out with only a quarter of a tank left, and there is a loss of power. could this be the fuel pump or fuel filter?

Answer
Sounds like a problem with the fuel pump components in the fuel tank. Especially look at the small rubber hose that connects the pump to the pickup tube for being loose and sucking air.

The fuel pumps are well noted to start to fail around 40,000 miles.
