Note about soft failures on the fuel pump
Some of the fuel pumps are soft failing. This means they work and you do not have issues starting your car, but they can cause intermittent hesitation, misfiring, stalling as well as problems running out of fuel when the tank is about 1/4 full. This is due to low pressure and/or volume causing the siphon or suction jet pump that transfers fuel from one side of the tank to the pump side to not transfer fuel correctly. What happens is you still have fuel in the non electric pump side, but the electric pump side runs out of fuel. This usually happens with 1/4 of fuel showing on the gauge. The hesitation, misfiring and stalling is usually again to low pressure and/or volume from a weak fuel pump. Many have recently replaced their fuel pump & filter as preventative and found that they have crisper throttle response and better overall acceleration, which was not noticed until the pump and filter were replaced. So there may in fact be some hidden benefits to preventatively replacing your fuel pump and filter.
