Bad Fuel Pump: Any suggestions before buying a new one?

Well at least you finally got to the bottom of it (pun intended). I forgot that little piece of rubber hose was back there (good pics !). Guess it doesn't do much good when it falls off ! Back in the days of mechanical fuel pumps on the engine I have seen a lot of good pumps get replaced when the culprit was really a rotten pickup hose near the tank sucking air. The weird thing is, they would never leak a drop of gas.
 
at alternative auto in michigan ,they are using the Ford SVT foucus fuel pump in fox mustangs, and they are one of the best mustang shops in the country,, you could eat off the floor in the place
