Once you have the lines, fuel hoses and elelectrcal disconnected, the tank drops down in the back just enough to clear the differential, then slides back so the front of the tank clears the frame crossmember. Remember to disconnect the two fuel line quick connects in the front (one fuel pressure, the other fuel return). If you pull the driveshaft and the heat shield mounted on the tank, it gives you some addition room, but without a lift, it's a bi_ _h. I really helps if the tank is empty . . . . On the pickups, it's easier to raise the pickup bed off the frame to replace the pump/sender. D
