    Should have went with RX7 pump- cheap and very quiet.

    I would go with a relay for sure. You might check out my Mikuni thread for a write up. You should have the proper power supply behind your heater control panel - green and black wire.

    Actually i have not yet purchased the pump, any pump will do, as long as it does these:

    1) feeds the triples
    2) has return line
    3) easy to install
    4) quite affordable

    If you go into the Carb section (Mikuni) you will find lots of info - I would install one of these without a doubt just in case. Mounted my switch on the fire wall below the wiper switch. I did not pull the power from the pre ran wiring. Just in case I were to have an accident I wanted the power cut from the pump immediately! The Carter pump in a little loud at idle inside the car - but as soon as you go you can't hear it due to the music from the Mikuni's. Anymore I don't even listen to the radio - exhaust tone is the best!

    1)Rx7 pump is perfect for triples, but you should probably run a regulator
    2) you mean the regulator has a return? My set up dead heads at the carbs
    3) depends where you put it
    4) 35$

    I already own this Holley regulator, so yes im putting it in http://www.jegs.com/images/photos/50...510-12-803.jpg

    Im using the stock fuel piping, so i meant that the fuel pump has return. I'll have to look into those RX7 pumps, might not be that cheap here. Carters are 150$ at cheapest.

    You can get a Carter fuel pump for the RX-7 if this is the one: http://www.summitracing.com/parts/cr...zda/model/rx-7

    Carter is still made in USA. Recently read an article online about Federal Mogul selling the Carter division (and the Carter factory). F-M spokesman said they're getting rid of factories in all countries with high labor costs (and adult workers?). According to the article, the new owners will continue making fuel pumps at the USA factory with the same employees.

    I've had no issues with the el-cheapo fuel pump and its nice & quiet! My only complaint is the mounting bracket.

    Might be worth trying, as the price is so low. Still hoping if you guys have plenty of more pictures of different fuel pumps installed on Z lol

You might want to at least isolate the rail by replacing the steel spacers with a heat resistant material that doesn't conduct as well.

    I could only run 20 minutes on the track before I started having symptoms.

    As always YMMV. Good luck with the triple swap. It will sound glorious!

    Im quite positive that vapor lock is not issue here, not even hottest summer day. I live 100 miles from arctic circle... I just got new linkage from Pierce Manifolds, now all i need is that fuel pump...

    Probably work fine. Most triples only need about 3.5psi to run. I guess the worry would be flow- if there's enough.
    I thought the 73 pump was a supplemental pump for the mechanical.

    I run the Carter pump in my race car and it works great. My installation won't really help you though. I run a surge tank to maximize the range. Before the surge tank, I could only run about 1:40 on a tank, but now I can run a full 2 hours which is our driver stint limit. I run a Facet pump to get the fuel into the surge tank and then the Carter pump to feed the engine. The Carter is fairly loud, but it is inside the car. The Facet is much louder and it's under the car.

    I put the Carter P4070 in my car (which has triple Webers) last summer as the pump I had ran too much pressure and not enough volume. I had a regulator, but I got tired of playing with it. I put in the Carter, took out the regulator, put the return line back, and it supples the 3-4 PSI rock solid all day long. It is loud, even with the insulation mounts, but that just lets me know it's running! Also, I ran a separate power line to it, which also keeps it happy and I can shut it down when I want to.

    I mounted it on the outside of the car, bolted to the spare tire well...maybe a different location would have been better (i.e. quieter).

    I wonder could you install it on engine bay...? At least it would not be so loud inside the cabin

    I think that's a fairly popular pump in the Z world.

    BTW, why the name change?

    Haha, its a long story. My nick used to be the name of my band, which broke just recently.

    Anyone got experience on the Nismo pump? Heard that this same pump was in C10 GT-R

    Reverend, I'm using the cheapo RX-7 inline pump for a year now with no problems feeding my triples, I have used the Holley pump you linked to, can't remember if it was the blue or the red one but it was very loud.
    The RX-7 pump is rated at 4 psi continuous, I found it to be more like 3.5psi so I just opened up the regulator wide with no restrictions and everything is working well.

    Are you guys using junkyard RX7 pumps or buying new/reman ones? Around here, RX7's are just as scarce as Z cars and they simply aren't to be found in junkyards.

    When I installed my RX7 pump it was only putting out about 2 psi on my fuel system, your results may vary, but I went with an internally regulated Mallory pump and it was very quiet and puts out 3.5 psia reliabily.

    I've heard a lot of good about the Mallory pumps, too bad they cost twice more than any of the others. But they supposed to be quiet AND reliable.. cant afford both.

    I've got a Mallory pump 4070LP, it is quiet (you can barely hear it at idle) but I've never been able to get more than 2psi out of it for some reason no matter what I was doing to get higher pressure. Despite low pressure, flow was good.

    Well i now have that new pump. Its the Airtex/Webcon inline "el-cheapo" pump. Supposed to deliver up to 130liters/hour at 5-9psi. Installed it to same place as Dave, at the differential mount. Fits perfectly. Now i just need to tinker the electrics. Im not going to put any fancy inertia switches etc. Too complicated for my brains.

    I tried the Carter pump, but removed it due to the noise. It's like someone is using a hammer drill on the underside of the car!

    I switched to a Pierburg many years ago, It's been faultless on road and track.

    Pierburg roller cell pump, 1.9 litres per minute @ 3 psi running at 13.8 volts 2.0 amps and supports up to 340hp.

    This is more electrical related but i wouldnt want to start a new topic. I've now connected the pump to the harness (black and green wire) but i need to know whats next. I suck at electrics so i need some advice. Im not putting any oil pressure switches so can i just skip it and do the rest from this schematic?

    Yes, Green to the relay(87) and ignition to relay(86) like on the pic. but you know, if you have an accident, you have to switch off ignition to stop the pump. just saying.

    That black and green should be behind your radio and is probably not a complete circuit. You will have to complete the circuit so pump will come on with ignition.

    You'll get voltage drops using the factory harness without a relay, so much you can actually hear the pump speed up and slow down when the indicators come on/off. Ask me how I know, Lol! Lower voltage means more current draw which may shorten the life of the pump. It'll also alter the flow rate.
