Metering Rods - .070 x .037

The Edelbrock Metering Rods - .070 x .037 are precision fuel delivery components designed for carburetor tuning and performance optimization. These rods are essential for automotive enthusiasts and mechanics who aim to fine-tune air-fuel mixture ratios across various engine loads and RPM ranges. Whether you're working on a freshly rebuilt carburetor or adjusting fuel delivery on a modified engine, these rods provide the precise control needed for optimal drivability and efficiency.

Metering rods modulate fuel flow through the main jet circuit as the throttle opens and engine demand increases. The .070 inch outer diameter and .037 inch inner diameter specifications determine the taper profile and fuel passage area, directly influencing how the carburetor responds to acceleration and cruise conditions. Edelbrock's precision manufacturing ensures consistent taper geometry, allowing for methodical swapping of rod sizes to achieve the desired mixture correction for specific engine combinations.

Carburetor tuners, engine builders, and performance mechanics rely on Edelbrock metering rods to address mixture issues that may arise from cam changes, intake modifications, or altitude variations. Installation involves removing the float bowl and throttle body linkage, then seating the rods in their corresponding holds. These rods are typically paired with matching jets to create a calibrated fuel curve that maintains proper combustion across the RPM band.
