wondering if anyone can help with info for replacing the elec fuel pump on the 73 240z. nissan dealer says no pumps available. looking for advice on a suitable replacement. thanks

Try this.

If you must have a OEM pump , this wont be for you because they look different. However a electric fuel pump from a RX-7 works great. It must be for a carburated engine not injected. I have run these for 8 years in my Z with SUs. They pump 4 psi. $15.00 at the u-pull-it. We have used one on a stroker engine with triples and it supplied those also. Gary do a search there is plenty of info on this topic.

Does the RX-7 pump link up fairly easily?

Thanks for the help, I would like to keep the car as original as possible, my dad bought it new in 73, he rebuilt the engine about 1990 and it has been stored since then. I'm trying to get it running again. Then the usual rust problems will need to be fixed but I think it will be worth the effort.

I see Facet makes a solid state elec fuel pump.. on JC Whitney for about $100. 2.75-4.0 psi, wondering if any has had any experience with it.

You need to make a little bracket to mount it . I just went to Home Depot and bought a length of steel strap about 1/8'' thick and 1 1/4'' wide and cut a 12'' piece off. put two 90* bends to allow clearance for the moustache bar and bolted it to the flat plate next to the Moustache bar. I used the rubber mountings that came with the pump. I pulled the pump at the bone yard. When I pulled the pump I cut as much wire as I could. I used the RX connections and soldered the wires to the Z wires . Green is the hot and black is the ground. Add a new filter between the pump and the tank. Easy mod. Pump $15.00 at the B Yard and I think the filter was about $6.00. The pump is quiet and puts out about 4 psi. Dough IFyou can find a OEM pump they run right about $135.00. Gary

You said you wanted to keep the Z OEM ! ?? J C Whitney is far from OEM:stupid:

Would like to stick with OEM pump but cant seem to locate one so far.

So.. does the 73 have a elec and a engine driven fuel pump? Does the 73 need a elec if using 72 round tops?

Just wondering. I am 2000 miles from my car right now, not to lazy to go look.:bandit:

On the '73 the factory installed the electric fuel pump to help with the problem of the fuel boiling in the fuel rail. By circulating gas from the tank through the engine mounted pump, that adds heat, and the fuel rail it helped greatly to solve the problem. The flat top carbs didn't help , it was a combination of the two. I have been running only the electric all along. By the way Nissan provided the wiring for the pump back by the gas tank on the '71 on I am not sure about the earlier Zs. The wires are tucked up by the tank and taped with blue tape by the wires that go to the sending unit for your gage. Side note : if your OEM manual pump fails , Nissan still has the rubber diaphragm that is needed to fix the problem. Gary

Thanks Gary,

That make sense. So if the OEM quits I can bypass and run until I replace the elec pump right?

Thanks
