Replace fuel pump in 2001 Sport Trac. I should have taken pictures. Time: 3-4 hours.
-Pull fuel pump relay and turn over engine to depressure fuel system.
-Remove negative battery cable and secure.
-Siphon as much gas out as possible, easiest to remove fuel filler hose from rear of gas tank and siphon with a 6' piece of garden hose. Disconnect smaller vent hose too.
-Support rear of truck with jack stands. Support fuel tank with jack.
-Remove rear driver side wheel, mud gaurd flap, and plastic wheel-well liner.
-Remove 2 front tank mount bolts. Remove rear tank support strap bolt and strap (you have to kind of bend and twist it out of the way, it has a tee shaped end that locks into a slot on the driver's side, it should fall out when you turn it in the slot).
-Pull wire connector mounted to frame above tank to give plenty of slack before lowering the tank.
-Slowly lower the tank until you can reach the: wire connector on tank (disconnect it); main fuel line connector (disconnect it, on mine it was a plastic connector with a couple small push tabs); vapor line connector (disconnect it).
-Lower and remove the fuel tank. Clean off the top of the tank so no junk gets in when you pull the pump assy.
-Note the pump assy. cover alignment arrow and reference bump for proper re-assembly.
-Pull the pump assy and replace, or just replace the pump. Get a new strainer too.
-Clean and oil the hatch gasket and re-install the pump/sender unit.
***-The fuel pump discharge hose between the tank and the steel fuel line on the frame is lame stiff nylon and probably got kinked when you lowered the tank (mine did). Replace it with a short piece of rubber high-pressure fuel line using the original connectors with hose clamps.***
-Raise the tank with the jack and slide the forward mount into place and loosly install the 2 front mount bolts.
-Lower the tank again so you can connect the wire connector; fuel line connector; and vapor line connector.
-Raise the tank and connect the fuel filler and vent hoses and replace the wire connector mount to the frame above the tank.
-Re-install the rear tank mount strap and tighten all tank mount bolts.
-Replace the fuel filter.
-Re-install the fuel pump relay and negative battery connector. Start it up and check for leaks before you put the wheel and stuff back on.
