my car pump
I have a 1971 240z. the wires for an electric pump are in the car from the factory. Look at the wire harness in the back of the car. You need to be under the car looking up at the fuel tank sending unit and the wires that attach to the fuel tank. You should see some blue colored plastic tape on the harness. undo that blue tape. under the tape are the wires for the fuel pump. if you look up on the bottom of the floor/frame sections you will see some threaded holes, those holes are to bolt the fuel pump mounting bracket onto -- electric fuel pumps, and the bracket for carbureted cars are most commonly found on 260zs.. but if guys like me have gotten a hold of the car, you may find bracket and pump on any 240 or 260.
the fuel pump from nissan has a built in intake side fuel filter, check valves to prevent fuel drain back, and is regulated to about 4 psi all in one package. cost for this pump is over $75. I also have a 1972 510 with side draft webers and i use two of these pumps in parallel. I have had no problems with these pumps. they are quiet. and if you have the proper brackets, bolt right on.
the wires for the other end are located behind the radio/heater control panel. another blue tape on the harness will be around the other end of the wires for the fuel pump, check wire color codes to make sure you have the fuel pump wires and not the fog light wires. you will have to make a connector to run the ground connection and fuse box connection.. under the heater/ radio panel.
