Electric fuel pump on 72Z w/carb problems

[Curtis240Z]

Any idea if this is true for a 73' or if the 73' even came stock with an E.P.?

Yes '73 came from the factory with an electric fuel pump along with the mechanical one. I word of caution all years 240Zs come with electric fuel pump wiring but not the rpm relay if it wasn't from the factory.

Good to know. I'll ahve to attack that somtime in the near future. I don't wanna end up a fireball on some back road.

For one thing the AC pump is a good pump if you can stand the noise. The stock electric and the one from the early '80s RX- 7 are turbine pumps and are pusher pumps and work the best near the tank and they are quiet. Always install a inline filter before the pump, they run at high speed and crud really messes them up. There is stock wireing on the '72 for a electric pump . you will find it wound up and taped with blue tape , just follow the sending unit wire up the side of the tank. I would remove the screens from the entake of the carbs and leave them out. I am running a electric only on my Z and have no problem. On another note try 20w in the carbs the 5w of the atf is too thin and can cause a lean condition off the line. Just for a split secound. By the way you should be able to find a RX-7 pump at the bone yard for about $15.00. I have tried this pump on a tripple set up and no problem , they put out right at 4psi. If you do the RX pump be sure it is from a carbed car not injected! my2c Gary

Gary,

Any idea if an early '71 has the wiring for an electric pump built in? I need to get mine isntalled real soon.

Marty, while I'm not using the fuel pump wiring now, I did find it on my early '71. I've heard that even the very early low-VIN cars have the wiring, so I'm pretty sure that your '71 has it as well.

Thanks Arne. I'll have to have a look under there this weeken.

Yes it does, same as described previously, the other end of the conection is a wiring plug at the dash next to the heater console. The wires that need to be jumped are black and green. They are part of a plug that is located in the wiring bundle on the rh side. Make sure and fuse it, and use a relay for safety
