Dual Feed Fuel Log Adj. 4150/4500 Series Carbs

The Edelbrock Dual Feed Fuel Log for 4150/4500 Series carburetors is a precision aluminum fuel distribution manifold engineered to balance fuel supply across dual inlet ports on Holley-style carburetors. This black anodized component addresses a critical issue in high-performance carburetor setups: uneven fuel distribution between primary and secondary circuits, which can lead to lean conditions, stumbling, and inconsistent jetting across engine load ranges. Built from lightweight aluminum and finished in corrosion-resistant black anodize, this fuel log maintains consistent flow rates while the adjustable length design accommodates varied engine bay layouts and fuel line routing requirements.

The fuel log features dual 8 AN female inlets that accept standard -8 fuel lines, dual 7/8-20 inch male outlets that thread directly into Holley 4150/4500 carburetor fuel ports, and a 1/8 inch NPT gauge port for fuel pressure monitoring. The adjustable length design allows tuners to position the manifold for optimal packaging without sacrificing flow characteristics. The 1.39 lb weight keeps fuel system mass minimal, important in engine conversions and weight-sensitive builds. Dual feed design ensures both carburetor circuits receive regulated fuel at balanced pressure, critical when running vacuum-secondary or mechanical-secondary carburetors at high RPM or under heavy load.

This manifold is essential for builders upgrading to 4150/4500 carburetors on street engines, bracket racing platforms, and vintage muscle car restorations where fuel consistency directly impacts throttle response and part-throttle drivability. The gauge port allows real-time fuel pressure verification during dyno tuning or track sessions, enabling precise fuel regulator adjustment without trial-and-error jetting. Edelbrock's reputation in carburetor fuel management makes this component a trusted choice for serious enthusiasts who prioritize balanced fuel delivery over cheaper single-feed alternatives.
