rolmsted Posted December 5, 2015 Share Posted December 5, 2015 I bought an almost complete EFI setup to swap into my 240z. But haven't been able to find the main efi relay. I have a complete carb set up that I just couldn't dial in. Possible partial trade? Quote Link to comment Share on other sites More sharing options...
NewZed Posted December 5, 2015 Share Posted December 5, 2015 I bought an almost complete EFI setup ....... But haven't been able to find the main efi relay Early 280Z, late 280Z, or 280ZX? They all use a different EFI relay. If you studied the wiring diagram you'd probably realize that you can work around it. Half of the early Z relay is the fuel pump relay.

rolmsted Posted December 22, 2015 Author Share Posted December 22, 2015 Sorry got busy for last 2 weeks, its a 1975 set up, I was looking at the diagram and drew it up and saw its two separate relays inside one. I'm at work so don't have the diagram I drew, Ill come back and post tonight to make sure its correct. What amp relays would I need? Quote Link to comment Share on other sites More sharing options...
NewZed Posted December 22, 2015 Share Posted December 22, 2015 Match the fuses or go a little higher. There are two separate plugs to the dual relay, if you wanted to replace just half/one. Here's a potential source - http://www.datsunstore.com/relay-fuel-injection-7577-fuel-pump-p-735.html Quote Link to comment Share on other sites More sharing options...
redbull z Posted January 21, 2016 Share Posted January 21, 2016 I have a fuel pump relay for a 76 if needed Quote Link to comment Share on other sites More sharing options...
