Primary Metering Jets .073in

The primary metering jets .073in from Edelbrock are precision brass fuel-metering components engineered for carburetor tuning and jetting optimization on Quadrajet-equipped engines. These jets are essential for mechanics and enthusiasts who demand precise fuel delivery calibration, whether you're rebuilding a classic muscle car, restoring a street rod, or fine-tuning a performance application. Available as a pair, these jets allow you to dial in the exact fuel mixture your engine requires across the RPM range, ensuring peak efficiency and response.

Machined from brass for durability and chemical resistance, the .073-inch orifice diameter controls the flow rate of fuel through the primary metering circuit in Quadrajet carburetors. The precision bore ensures consistent atomization and fuel atomization patterns critical to proper combustion at cruise and part-throttle conditions. This specific sizing is ideal for engines requiring leaner jetting than stock, making these jets popular for improved fuel economy, emissions compliance, or adaptation to alternative fuels and higher-octane blends. The compact design—measuring 1.7 x 1.2 x 5.1 inches—allows easy installation and removal during carburetor service and tuning sessions.

Carburetor technicians, restoration shops, and dedicated engine builders rely on Edelbrock metering jets to match fuel delivery to specific displacement, camshaft profiles, and intake manifold combinations. These jets are compatible with any Quadrajet four-barrel carburetor and integrate seamlessly into rebuild kits or standalone tuning upgrades. Whether you're chasing better driveability in traffic, maximizing highway mileage, or recovering lost performance from a rebuilt engine, proper jetting is non-negotiable—and these precision brass components deliver the repeatability and accuracy you need for dependable results.
