    EFI Regulators

    Designed for use on regular EFI systems requiring one feed line to the fuel rails and one return line to the fuel tank. Wrench flats on the 10686 model make it easy to install pipe fittings. Adjustable from 25 to 75 psi. Bottom port is the bypass back to the fuel tank. Two ports on sides can be either inlet or outlet. Fuel pressure will rise on a 1:1 ratio when referencing boost. Stainless Steel Bracket & Screws.
    Note: The 10685 regulator is designed to use O-ring style fittings on the inlet and outlet ports. It is supplied with three O-rings for use on port fittings. The port threads are the same as -6AN fittings. For example, you can use a Professional Products -6AN Flare Union fitting in these ports (#15216 blue, #16216 black, or #17216 polished). If you need a 90° style fitting, #71285 (black only) includes a jam nut and O-ring. This design allows you to thread the fitting into the position you want and lock it down with the jam nut.


    25-75 PSI

    Professional Products Powerflow Fuel Pressure Regulators are designed to help stabilize fuel pressure under the most demanding conditions. Available for a number of applications, these regulators allow multiple fuel pressure adjustments to increase volume for better overall vehicle performance.
