Please tell me the easiest way to replace my bad fuel pump and sending unit
in my chevy celebrity wagon 3.1
its really not to hard...to drop tank. ...Disconnect wiring from the tank. Remove the ground wire retaining screw from under the body. Disconnect all hoses from the tank. Support the tank on a jack and remove the retaining strap nuts. Lower the tank and remove it. Notice the position of the filter for replacement. Support the pump with one hand and grasp the filter with the other. Rotate the filter in one direction, then pull off of the pump. Discard the filter. Disconnect the fuel pump connector, on wagons it will not be necessary. On all models excluding wagons: Place the sending unit on a bench upside down, then pull the fuel pump downwards to remove from the mounting bracket. Tilt the pump outwards and remove from the pulsator. On wagons proceed as follows: Disconnect the negative terminal nut and lead (black) from the pump. Disconnect the positive lead (gray) from the pump, then loosen the coupler clamps. To install: On all models excluding wagons: Assemble the rubber bumper and insulator onto the pump. Position the fuel sender assembly upside down and install the fuel pump between the pulsator and mounting bracket. Connect the pump electrical connector. On all wagon models: Position the fuel sender assembly upside down and install the coupler and coupler clamps to the inlet tube, but do not tighten at this time. Install the pump between the coupler and the mounting bracket, then tighten the clamps so that 5-8 teeth are engaged. Attach the positive lead (gray) to its positive terminal with the nut, then attach the negative lead (black) to the negative terminal.Always install a new filter when installing a new pump. Position the pump filter on the new pump and push the outer edge of the ferrule until it is fully seated. Install the sending unit. Install the gas tank and check for leaks. Reconnect the battery cable.
