Metering Rods - .068 x .052

The Edelbrock Metering Rods – .068 x .052 (Part Number 1448) are precision brass carburetor components engineered to control fuel delivery in Edelbrock carburetors. Supplied as a pair, these metering rods are critical tuning elements that regulate the air-fuel mixture across the engine's operating range, directly affecting throttle response, fuel economy, and engine performance on the water.

The .068 outer diameter and .052 inner diameter specifications define the orifice size through which fuel flows under vacuum-controlled conditions. Brass construction provides corrosion resistance in marine environments where salt spray and humidity accelerate oxidation of ferrous metals. The tapered profile of metering rods creates a precise relationship between engine load and fuel enrichment—as the engine pulls harder, the rod retracts further into the jet, allowing more fuel to flow. This variable control eliminates the need for fixed jets alone, delivering better throttle modulation and part-throttle economy compared to static orifice designs.

Replacement metering rods are essential when tuning an Edelbrock carburetor for different engine builds, fuel types, or altitude conditions. Weekend fishermen running stock engines benefit from OEM-spec rods, while serious offshore anglers and performance boaters rebuilding carburetors after season-long salt-water exposure need quality replacements to restore precise fuel metering. These rods are also critical during carburetor restoration, as original components may wear or become damaged from ethanol fuel breakdown or corrosion.

Edelbrock metering rods for sale as OEM-equivalent service parts ensure that your carburetor tuning remains accurate across idle, cruise, and wide-open throttle conditions. Proper metering rod selection is fundamental to carburetor performance—mismatched sizes result in either lean surging on acceleration or fouled plugs from over-enrichment at cruise. This pair fits all compatible Edelbrock four-barrel and two-barrel carburetor models using 1448-specification metering rods.
