TheBlaiant Posted July 10, 2012 Share Posted July 10, 2012 I'm going to set up an external fuel pump and sump my gas tank, the only thing I want to know is if the stock 260z pump would keep the car running, it'll be the first time it starts in a few years.

NewZed Posted July 10, 2012 Share Posted July 10, 2012 The 260Z pump is a low pressure pump for carbs. EFI came with the 280Z in 1975. You need a high pressure pump with the appropriate FPR. And you should be measuring fuel pressure before you even try to start the car, to be sure things are right. Unless you've done some plumbing and added a return line, you could get too high fuel pressure (from your new EFI pump) due to back pressure from a too small return line. I haven't done what you're doing, these are just odds and ends I've picked up from the forum. Quote Link to comment Share on other sites More sharing options...
