Dual Inlet Fuel Line Kit Holley 4150 Black Anod.

The Dual Inlet Fuel Line Kit Holley 4150 Black Anod from THE BLOWER SHOP is a critical fuel delivery system upgrade for carbureted performance engines running Holley 4-barrel carburetors. Designed for enthusiasts building high-horsepower naturally aspirated or supercharged engines, this kit solves a common problem: delivering adequate fuel volume to dual carburetors or fuel bowls while maintaining clean, organized engine bay aesthetics. Whether you're tuning a street machine, bracket racer, or classic hot rod, proper fuel line routing directly impacts carburetor performance, fuel pressure stability, and overall engine reliability.

This kit features black anodized aluminum construction, which resists corrosion and maintains a professional appearance under hood while handling fuel system pressures typical of Holley 4150 carburetors (typically 4.5–7 psi). The dual inlet design allows fuel to enter the carburetor from two separate points, improving distribution across fuel bowls and reducing lean spots during acceleration or high-G cornering. The anodized finish protects against fuel degradation and UV exposure, ensuring long-term durability in both street and race environments. Aluminum construction keeps weight minimal—critical for performance builds where every pound matters.

This fuel line kit is ideal for engine builders, carburetor specialists, and performance enthusiasts upgrading fuel delivery on Holley 4150-equipped vehicles. Installation requires basic fuel system knowledge and proper fuel line fittings (typically -6 AN or -8 AN, depending on your fuel pump output). The compact dimensions (8.85 x 6.8 x 14.4 inches) ensure routing flexibility in tight engine bays, while the 2.03 lb weight contributes negligibly to overall vehicle mass. Compatible with both mechanical and electric fuel pumps, this kit integrates seamlessly into street, strip, and marine applications where Holley carburetors are the standard choice for proven, tunable performance.
