.035in Bypass Pill Main Jet

The ENDERLE .035 inch Bypass Pill Main Jet (part number 7009-35) is a precision fuel metering component designed for carburetor tuning and engine calibration on high-performance racing and specialty engines. This bypass pill jet functions as a critical calibration component in carburetor fuel delivery systems, allowing tuners to fine-tune fuel mixture ratios by controlling bypass fuel flow rates during acceleration and transient conditions.

Manufactured from brass, the .035 inch ID (internal diameter) specification establishes a precise flow restriction that works in conjunction with other main jet elements to achieve the target air-fuel ratio across engine load ranges. The compact dimensions (1.7 x 0.6 x 1.85 inches) and lightweight construction (0.05 lbs) allow seamless integration into existing carburetor assemblies. Bypass pills are essential for drag racing, oval-track competition, marine performance builds, and custom engine applications where factory calibration does not meet performance demands or altitude/temperature conditions differ from original specifications.

ENDERLE carburetor components are widely recognized in the racing and high-performance engine tuning community for precision manufacturing and consistency. This .035 inch bypass pill main jet serves engine builders, professional tuners, and serious enthusiasts who require exact fuel metering control. Proper selection of bypass pill size is critical—oversized pills restrict fuel flow excessively, while undersized options lean the mixture during acceleration, both conditions risking engine damage. Buy this ENDERLE main jet component individually as a replacement part or for precision carburetor recalibration on racing engines, fuel-injected conversions, or specialty builds requiring OEM-equivalent calibration hardware.
