Mudge Posted December 11, 2002 Share Posted December 11, 2002 I remember reading somewhere about people using an RX7 fuel pump, external, for carb, but don't remember the year spread. Anyone remember this? Quote Link to comment Share on other sites More sharing options...
Hybrid240z Posted December 12, 2002 Share Posted December 12, 2002 Hey Mudge...I have heard the same thing and that you have to use one from a first gen RX7, the one with a carburetor. I also want some more info on this since I am thinking of doing the same swap. Does anyone out there have pics of their setup? Did you run a regulator or return line? How reliable is it? Thanks, Marcos Quote Link to comment Share on other sites More sharing options...
fl327 Posted December 12, 2002 Share Posted December 12, 2002 i heard you can just run it how it is with a small holley regulator, its the 79 i think, it has a four barrel carb. Quote Link to comment Share on other sites More sharing options...
Mudge Posted December 24, 2002 Author Share Posted December 24, 2002 I forgot what page it was on, here we go: I had trouble finding an electric fuel pump that worked at low pressures. But then I remembered that the early '80s Mazda RX-7 used a 4-barrel carb and had a 7000 redline. Suspecting it might be perfect for a Z, I read the shop manual specs which quoted 3.7- 4.7 psi. Perfect! I got it for $15 from my junkyard, it's quiet and powerful. Always mount an electric pump as close to the gas tank as you can. It's better to "push" the gas rather than "pull". http://www.geocities.com/motorcity/2824/engine.html Quote Link to comment Share on other sites More sharing options...
