  • Holley Fuel Pressure Regulators

    These Holley Fuel Pressure Regulators are great for adjusting for fuel pressure requirements of various carburetors. Having too much fuel pressure present at the inlet of the carburetor will cause the needle and seat to stay open resulting in flooding and driveability issues.

    Holley Standard Pressure Regulator
    Recommended for low-pressure applications that require steady flow. Fuel pressure regulators are factory adjusted by Holley to 2.7 psi with a 1-4 psi range. Accepts 3/8" NPT fittings.

    Holley Max Pressure Regulator
    Adjusts from 4.5 to 9 psi. Also good as a high-pressure bypass. 2 regulators are recommended for dual 4-barrel applications. Accepts 3/8" NPT fittings.

    Holley Big-Port Regulator
    Die-cast aluminum regulator adjusts from 4.5 to 9 psi. Least restrictive, highest flowing production regulator with one 1/2" NPT inlet port and two 1/2" NPT outlet ports. Mounting hardware included.

    Manufacturer's Part Number:
    12-704
    Rated 5 out of 5 by from Works and flows great ! I bought this to replace the 803 Holly regulator. The new 704 flows way more fuel and holds a more consistent pressure than the old. More more pressure drop at full throttle.
