K-Jet .150

The K-Jet .150 is a precision fuel metering jet manufactured by Kinsler, designed for tuners and engine builders who demand exact control over fuel delivery in high-performance fuel injection systems. This component is essential for carburetor and fuel injection tuning, allowing you to dial in the exact air-fuel ratio your engine requires across different load ranges and RPM bands. Whether you're building a competition engine, restoring a classic with modern EFI, or optimizing an existing fuel system, the K-Jet .150 provides the metering precision that separates a well-tuned engine from one running guesswork.

The .150 designation refers to the jet's orifice diameter in inches, controlling fuel flow rate through the metering circuit with repeatable accuracy. Kinsler jets are manufactured to exacting tolerances, ensuring that each unit delivers consistent fuel atomization and spray pattern—critical factors in combustion efficiency and engine response. The compact design fits standard Kinsler fuel injection manifolds and compatible aftermarket systems without modification.

The K-Jet .150 is ideal for street and strip builders running Kinsler fuel injection systems, as well as mechanics tuning Weber carburetors or other precision metering systems. This jet works by restricting fuel flow to a precise cross-sectional area, creating back-pressure that maintains stable fuel delivery even as engine load, boost pressure, and RPM fluctuate. Its design ensures that you can achieve the optimal air-fuel ratio for various performance applications.
