    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 10686 model replaces the previously offered 10670 and 10671. The 10686 not only looks different with a new exterior finish, the functionality of the regulator has been improved.
