Metering Jets .100

The Edelbrock Metering Jets .100 are precision fuel metering components designed for carburetor tuning and engine calibration. These jets control the exact flow rate of fuel through the carburetor's main circuit, directly influencing air-fuel mixture quality and engine performance characteristics. Whether you're rebuilding a classic carbureted engine, performing a restoration, or fine-tuning an existing setup, metering jets are essential wear items that often require replacement or upsizing during modification work.

The .100 designation refers to the jet's orifice diameter in hundredths of an inch—a critical specification that determines fuel delivery volume at cruise and part-throttle conditions. Edelbrock jets are manufactured to tight tolerances using brass construction, ensuring consistent metering and durability across engine cycles. A .100 jet is a mid-range size commonly used in street applications and mild to moderate performance builds; selecting the correct jet size depends on fuel pump pressure, carburetor model, intake manifold design, and desired air-fuel ratio.

Changing jet sizes allows tuners to compensate for altitude, fuel type, intake modifications, and exhaust system changes without requiring full carburetor replacement. Technicians and enthusiasts rebuilding Edelbrock four-barrel and two-barrel carburetors regularly stock multiple jet sizes to dial in optimal fueling for their specific platform. These jets are compatible with most Edelbrock carburetors and are essential for achieving the best performance in various driving conditions.
