    Fuel pressure regulator diy

    I have been reading the stickys and everyones input on the rrfpr,
    I have the tank adapter from Riva, the problem is it is hard to find a fuel pressure regulator that has a return line outlet??
    The riva tank adapter has a fuel outlet and an fuel return back in,
    99% of all the fuel pressure regulators just have the fuel in, fuel out, gauge port, and static line vacum for 1 to 1 rising rate,

    any ideas?
    thanks,

    Fuel out is the return.. You Tee the fuel in from the tank to the rail.
    Two ways to plumb it just disregard the Begi if you are not using one. I have been using the e-bay special for three seasons on several boats with no problems.

    I like the idea, I just thought that fuel had to go thru the regulator to be adjusted?
    In one side out the other and you could adjust the pressure up or down to change the AFR's?
    then a return line,

    So the fuel goes by the regulator with the "T" , then going back thru the regulator to the tank, that make adjustable?
    thanks,

    NO... The regulator purpose is to allow only so much fuel to return to the tank. It holds back pressure on the rail hence giving you fuel pressure. It hold fuel back until it reaches desired pressure and lets the rest go.... Make sense....
    I have the regulator that BD posted... 20.00 and it is rocking a long time later. Comes with a liquid filled gauge...
