  • Fuel Pressure Gauge!!!!!!

    Where can I purchase a fuel pressure gauge?? I am installing a set of Novi 44 and was wondering how do I measure the fuel pressure during idle and WOT?? How important is it to get the right amount of pressure at these throttle positions?? Do I adjust this pressure by adjusting the size of the return line restrictor?? Any info would be helpfull.

      I can't say I've ever seen one - what restrictor was recommended?

        Novi sells fuel pressure gauges. So does just about any automotive speed shop, Mc Master-Carr, and many other suppliers of guages.

        You need no more than 4 psi at idle, 6 psi at WOT.

          And yes, changing the return line restrictor is how you adjust fuel pressures.

            I was told by novi to run a #60 return jet. By increasing the size of the jet does that then lower the presuure and vise versa???
