Metering Rods - .068 x .057

The Edelbrock Metering Rods - .068 x .057 are precision carburetor components designed for tuners and engine builders who demand accurate fuel metering across the rpm band. These brass metering rods are sold as a pair and fit Edelbrock carburetors, making them essential for anyone rebuilding, restoring, or fine-tuning a classic or modified engine's fuel delivery system. Metering rods directly control the air-fuel mixture under part-throttle operation, influencing throttle response, fuel economy, and overall drivability.

These metering rods feature a .068-inch outer diameter with a .057-inch upper step, a geometry that works in tandem with Edelbrock's calibrated jets to modulate fuel flow as the throttle plates open. Brass construction provides durability and maintains dimensional stability under heat cycling, critical for consistent carburetor performance. The tapered profile of the rod restricts fuel passage progressively, allowing the carburetor to transition smoothly from idle to cruise to wide-open throttle without stumbling or flat spots. Proper metering rod selection ensures the engine leans out at cruise speeds while staying rich enough at acceleration to prevent hesitation.

Carburetor enthusiasts, street rod builders, and performance mechanics rely on Edelbrock metering rods when replacing worn originals or troubleshooting rich or lean running conditions. Installation requires carburetor removal and disassembly; these rods must match your specific Edelbrock carb model and jet configuration for optimal results. Whether you're chasing perfect cruise-speed mileage on a vintage build or dialing in a high-revving small-block, the correct metering rod diameter makes the difference between a smooth, predictable powerband and erratic fueling. Always verify compatibility with your exact carburetor before purchase.
