Holley 4150 Aluminum Fue l Log Red/Blue 3/8Innpt

The Holley 4150 Aluminum Fuel Log Red/Blue 3/8 inlet is a precision fuel distribution manifold designed for high-performance carbureted engines that demand reliable, balanced fuel delivery across multiple carburetors. Built for serious enthusiasts and professional engine builders, this fuel log serves as the critical junction point in dual-carb and multi-carb setups, ensuring each carburetor receives consistent fuel pressure and volume. The red and blue color-coding simplifies fuel circuit identification during installation and troubleshooting, reducing setup time and minimizing errors on the dyno or in the field.

Manufactured from lightweight aluminum, the Holley 4150 Aluminum Fuel Log delivers superior thermal stability and corrosion resistance compared to cast-iron alternatives, while reducing overall engine bay weight—a critical advantage in competition and street performance applications. The 3/8-inch inlet port accepts standard fuel supply lines and distributes fuel to multiple outlet ports with precision-engineered internal passages that minimize dead zones and pressure loss. Racing Power Co-Packaged engineering ensures dimensional accuracy and tight tolerances, allowing seamless integration with Holley 4150 carburetors and compatible fuel system components.

This fuel log is ideal for carbureted street rods, classic muscle cars, circle track racing, and street/strip dual-carburetor applications where balanced fuel distribution and reliability are non-negotiable. Installation requires standard fuel line adapters and a regulated fuel system capable of maintaining consistent pressure across all carburetor circuits. Compact dimensions (7.8 x 1.15 x 17.5 inches) and lightweight construction (1.28 lbs) make it suitable for tight engine compartments while maintaining the structural integrity demanded by high-RPM, high-fuel-flow environments.
