Recommendable Electric Fuel Pump 3.5 to 4 psi for Datsun 240z with dual SU carbs
Have seen different options for replacing my AIRTEX 8012S 5.5 to 9psi electric fuel pump for my 1972 240z. I am narrowing my decisión to the following:
Facet Electric Fuel Pump 1x Facet 476087 Silver Top Cylindrical Fuel Pump (STS504) (Facet STS504) from Green Spark Plug or Carter Electric Fuel Pump - In-Line Part Number: 8566-03413007 79 1979 Mazda RX7 Fuel Pump - Fuel Delivery - AC Delco, Airtex, Autobest, Carter, Delphi, Mr Gasket, Precise, In-Line - PartsGeek I need a pump that dials between 3.5 to 4 psi!! No more than this. It needs some power but not over 4 psi and that does not require a regulator. If there is any other better recommendations than any of these let me know also. |
Maybe you should be on a 240z forum? Just thinking, unless you have a rotary swap in it that is.

But always run a regulator. Return is best, but dead head is fine. The "self regulated" pumps never truly regulate properly. If nothing else a regulator will lengthen the life of the pump. |
The stock S2 RX-7 fuel pump is adequate for a 13B rotary with dual SU carbs. The carbs I used are late-1980's vintage HIF-6, with fuel return line. The 240z carbs are an older design and smaller.

I almost bought a twin SU intake set up a couple of years ago, but it turned out to be a scam... And that Carter pump would be perfect. Its a little noisy though. I like the weber redline series 8mm inlet and outlet pump too... |
