.110in Bypass Pill Main Jet

The .110in Bypass Pill Main Jet by ENDERLE is a precision fuel metering component designed for high-performance carburetor tuning in racing and tactical support vehicles. This micro-jet assembly serves operators, mechanics, and competition teams who demand exact fuel atomization control in variable load and altitude conditions. Built for demanding environments where marginal gains in fuel efficiency or throttle response directly impact mission capability or track performance, the bypass pill main jet represents decades of ENDERLE engineering refinement in carburetor technology.

This component functions as a critical metering orifice within ENDERLE's bypass fuel system, regulating pressure-compensated flow to the main discharge circuit. The .110-inch specification (approximately 2.79mm) is precision-drilled to exact tolerances, ensuring consistent fuel volume delivery across engine RPM ranges and load conditions. Constructed from corrosion-resistant material suitable for long-term storage in field conditions, the bypass pill main jet integrates seamlessly into ENDERLE carburetors used on both street and competition engines. Its diminutive size—just 0.5 inches across all dimensions—belies its critical role in preventing vapor lock, flood conditions, and lean-surge issues that compromise performance and reliability.

Technicians rebuilding or tuning ENDERLE fuel systems will find this main jet essential for carburetor restoration or performance recalibration. Replace or upgrade when experiencing erratic idle, bog on acceleration, or excessive fuel consumption—all indicators of worn metering jets. Compatibility with ENDERLE bypass-equipped carburetors requires verification of your specific model; consult factory documentation or contact ENDERLE technical support to confirm fitment. Installation requires disassembly of the carburetor body and careful seating to prevent fuel leakage; this component is not user-serviceable in most mobile or field conditions without proper shop equipment.
