Carburetor Fuel Inlet Kit w/Regulator. This inlet kit in black anodized aluminum fits Holley 4150 carburetors and has a -06 inlet. The kit incorporates a 10665 Fuel Pressure regulator into the overall design, simplifying the plumbing and eliminating the need for a remote mounted regulator.

Professional Products carburetor fuel inlet kits with regulator vastly simplify the plumbing and eliminate the need for a remote mounting of the regulator. All of the threads are 9/16-18 with O-ring seals, allowing for finite adjustment of all components, as well as simple replacement of the regulator, if needed. The inlet fitting on the bottom of the regulator easily swivels for either a front or rear-routed fuel line connection, and can also be repositioned to a right side assembly.
