.065in Bypass Pill Main Jet

The .065in Bypass Pill Main Jet is a precision fuel metering component designed for high-performance fuel injection and carburetor tuning systems. This brass jet serves as a critical control element for racers, engine builders, and tuning specialists who require exact fuel delivery calibration. The bypass pill design allows for controlled fuel bypass flow, making it essential for optimizing air-fuel ratios in competition and street performance applications where every tenth of a second counts.

Manufactured from durable brass, the .065in Bypass Pill Main Jet features a precisely engineered 0.065 inch internal diameter that regulates fuel flow with tight tolerances required for dependable engine performance. The brass construction provides excellent corrosion resistance and maintains dimensional stability across varying fuel types and temperatures. The main jet function controls the fuel-air mixture at cruise and part-throttle conditions, while the bypass pill restricts excessive fuel pressure, preventing overfueling and ensuring consistent atomization throughout engine operation.

This component benefits drag racers, circle track competitors, and serious street performance enthusiasts operating ENDERLE fuel systems or compatible injection platforms. Installation requires removal of the fuel bowl or metering block assembly, making it accessible for tuning adjustments without full system disassembly. The compact 0.5 x 0.5 x 0.5 inch dimensions ensure it fits standard fuel system housings. For optimal results, refer to your fuel system's tuning guide to select the correct jet size based on your engine displacement, boost level, and desired air-fuel ratio target.
