K-Jet .090

The Kinsler K-Jet .090 main pill is a precision brass metering component designed for high-performance fuel injection systems. With an internal diameter of 0.090 inches, this component functions as a critical flow-control element in tuned carburetor and fuel system setups, particularly in racing and performance applications where precise fuel delivery directly impacts engine performance and throttle response.

The .090 ID specification determines the fuel metering rate through the injector system. Kinsler's brass construction provides excellent durability and corrosion resistance in fuel-rich environments while maintaining the tight tolerances required for consistent jetting performance across engine load ranges. The compact dimensions (1.55 x 0.55 x 2.95 inches) and minimal weight (0.01 lbs) ensure minimal system complexity and easy installation in OEM or custom fuel delivery platforms. This individual pill component is sold as a single unit, allowing builders to dial in fuel mapping precisely for their specific engine displacement, boost level, and fuel system configuration.

The K-Jet .090 is intended for engine builders, fuel system technicians, and performance enthusiasts who require verified Kinsler metering components for carburetor jetting or electronic fuel injection tuning. Whether optimizing a naturally aspirated engine or fine-tuning a boosted application, selecting the correct main pill size is essential to prevent running too lean or excessively rich. This .090-inch bore size serves as a direct replacement or upgrade path for existing Kinsler fuel systems, making it an ideal choice for those maintaining or rebuilding proven performance setups.
