If your Mustang has a carburetor then it isn't hard at all to replace. On a carburated motor the fuel pump is located on the drivers side block at the front of the motor right behind the timing chain cover. All you need to do is disconnect the inlet and outlet fuel lines and the two bolts that hold the fuel pump to the block and pull the fuel pump off.
