Doc Hawk Posted December 11, 2007 Share Posted December 11, 2007 Is there a writeup for this conversion? I've searched all of the terms above in all their glorious combinations, and haven't found anything. I believe it would consist of the following simple steps: - Remove mechanical pump and install cover plate on head - Run a wire from the ignition "on" position to the electric fuel pump ... run through a relay? through an inertial switch? Opinions? - Install electric pump in the standard position under the car, right side, behind rear wheel, near tank. - Run a ground from pump to frame ... Ground at rear? Run ground back up to engine bay? - Install a fuel pressure regulator in the engine bay Anything missing, or is it that simple? Quote Link to comment Share on other sites More sharing options...

Also find out what fuel pressure your carbs need. And get the correct fuel pump and pressure regulator. Quote Link to comment Share on other sites More sharing options...
Pop N Wood Posted December 12, 2007 Share Posted December 12, 2007 Your Z should already have a power wire back by the tank were the electric fuel pump should go. You can get power off that. It has a ground also. The one thing highly recommended is to put in a fuel pump cut off in case you get in a wreck and the engine dies. The JTR manual recommends an oil pressure switch. You tap into the fuel pump power wire in the passenger's compartment footwell. I bought a Mr Gasket piece for a few dollars from Jegs. You can buy electric fuel pumps that are self requlating. Technically with such a pump you won't need a regulator and can even get by without a return line. Mallory's Comp 110 is such a pump. How elaborate you need to get sort of depends on how stout your engine is and wether you race it competitively. Here is a good site with more info than you are looking for http://www.centuryperformance.com/fuel.asp Quote Link to comment Share on other sites More sharing options...
