Metering Jets .104

The Metering Jets .104 is a precision carburetor jet designed for Edelbrock four-barrel carburetors and compatible fuel metering systems. These brass jets control the volume of fuel delivered through the main jet circuit, directly influencing engine fuel delivery at mid-range and high-throttle conditions. Sold as a pair, they are essential for carburetor tuning, jetting changes, or restoration work on classic vehicles and street machines that demand precise air-fuel ratio optimization.

Manufactured from brass, the .104 inch inside diameter jets meter fuel flow with exact orifice sizing to match specific engine displacement, altitude, and performance requirements. The nominal .104 ID (approximately 2.64mm) represents a mid-range jet size commonly used in stock and mildly modified engines seeking balanced fuel economy and throttle response. Edelbrock carburetor jets are interchange-compatible across many of their four-barrel models, and changing jet sizes allows tuners to fine-tune fuel delivery without replacing the entire carburetor—a cost-effective solution for dyno work, seasonal adjustments, or altitude compensation.

Carburetor enthusiasts, hot rodders, and engine builders rely on metering jets to achieve optimal performance across a range of engine speeds and load conditions. Whether you are restoring a classic muscle car, tuning a street engine, or adjusting for high-altitude driving, having the correct jet size eliminates rich or lean conditions that cause hesitation, stumble, or poor fuel economy. Installation is straightforward—jets are accessible from the float bowl and require only basic carburetor knowledge; always verify Edelbrock carburetor model compatibility and consult tuning guides to select the proper jet size for your specific engine and fuel system.
