Jeepjeff859 Posted November 28, 2015 Share Posted November 28, 2015 I'm confused on how a fuel pressure regulator should be installed. i have one that has duel inlets so is it supposed to be installed after the fuel pump and then to the fuel rail or is it line from the fuel pump supposed to go straight to the fuel rail and the a line going to the regulator?

MJ_Milam Posted November 30, 2015 Share Posted November 30, 2015 It's pretty simple. The top picture is correct. The existing fuel inlet line is your feed, the line facing down is your return and the line going right goes to your fuel rail and it looks like there's a nipple for the vacuum supply. That regulator doesn't have 2 inlets. Ones a supply and the other is a return. And if you're using this, you won't be using your stock FPR Link to comment Share on other sites More sharing options...
