Tomcat Posted April 28, 2008 Report Share Posted April 28, 2008 I just got this bike last week so I am still learning how everything works. From what I have read, this is the fuel pressure regulator. I see it has a fuel hose coming to it and one going back to the tank but can't find a diagram or picture that shows what the uncapped port is supposed to be connected to. I am assuming it should be hooked to a vacuum source to sense fuel requirements but that is just a guess at this point. Can anyone identify this connection for me. Thankyou.
