Carb Regulator/Filter Combo 10-Micron

The Carb Regulator/Filter Combo 10-Micron (Part #13226) is a precision fuel system component designed for vehicles requiring reliable pressure regulation and contamination control in a single integrated unit. This in-line regulator maintains consistent fuel pressure across the 3–20 PSI range while the integrated 10-micron filter element removes particulates that would otherwise damage injectors or carburetors. Built from black anodized aluminum, the unit combines durability with corrosion resistance for long-term reliability in demanding automotive applications.

The combo features 10 AN female O-ring inlet and outlet connections paired with a 6 AN female O-ring return line and 1/8-inch NPT diagnostic port. This configuration enables straightforward integration into custom fuel systems while the NPT port allows pressure gauges or dampers to be installed for real-time monitoring. The 10-micron filtration rating captures rust, varnish, and debris that accumulate in fuel tanks, protecting downstream components and extending the service life of fuel delivery systems. Aluminum construction keeps weight minimal while the black anodized finish resists oxidation in high-heat engine bays.

This regulator is suited for street rods, custom fuel injection conversions, carburetor upgrades, and performance builds where OEM fuel systems have been replaced or significantly modified. The 3–20 PSI range accommodates both traditional carburetors and low-pressure EFI systems, making it a versatile choice for engine builders and restoration specialists. Buyers working on fuel system custom builds will find the integrated filter particularly valuable, eliminating the need for a separate filter housing while reducing plumbing complexity. The NPT port enables future additions like fuel pressure gauges or pulsation dampers as system demands evolve.
