First, loosen the bolts on the battery cable’s negative connector to remove the connector from the battery terminal. Use a ratchet and socket to remove the bracket holding the fuel pump inside the tank. Make sure all fuel lines are connected to the fuel pump to prevent spillage. Carefully unscrew the nuts connecting the wiring to remove it from the old fuel pump.

Unscrew the retainer ring by turning it counter clockwise using a pair of channel locks to remove the old fuel pump. Connect the black wire to the negative terminal and the red wire to the positive terminal of the new fuel pump from the location of the old fuel pump. Unscrew the hose bolts from the filter and vent hose to disconnect the fuel lines from the old fuel pump before reconnecting them to the new one.

Place the new fuel pump where the old one used to sit. Make sure the mounting bracket holds the fuel pump securely in place before reconnecting the negative battery cables back to the terminals. While carrying out the procedure, take extra care because of the risks of working with electricity and gasoline. Keep a fire extinguisher on hand at all times.
