Gas Jet Extension (2pk)

The Quick Fuel Technology Gas Jet Extension 2-pack (part number 22-1QFT) is a precision carburetor tuning component designed for fine-tuning fuel delivery in carbureted engines. These screw-in jet extensions feature a 1/4-32 inch thread and are constructed from brass, making them resistant to fuel corrosion while maintaining excellent dimensional stability across temperature variations. Supplied as a pair with gaskets included, these extensions allow tuners to adjust jetting without replacing entire needle seats or main jets, preserving existing calibration points while extending fuel delivery range.

Carburetor tuning depends on precise fuel metering, and jet extensions serve a specific role in that process. The 1/4-32 thread specification is standard across Quick Fuel Technology's jet family, ensuring direct compatibility with Quick Fuel carburetors and comparable designs. The brass construction provides durability in high-fuel-flow applications while remaining machinable for custom modifications if needed. Each extension arrives complete with gasket seals, eliminating the need to source additional hardware. The compact dimensions—measuring 2.95 x 1.3 x 6 inches—allow installation in confined engine bays without interference.

This two-pack format addresses both primary and secondary jetting circuits or provides a spare set for test-and-tune sessions. Carburetor builders, performance engine shops, and fuel system technicians rely on jet extensions to achieve precise air-fuel ratios during dyno testing or street tuning. The pair quantity is particularly valuable for high-performance carburetors that run multiple jetting circuits, allowing matching extension sizes across the fuel system without mixing generations or suppliers.

Quick Fuel Technology has maintained a reputation for precision carburetor components since the 1970s, with jet extensions and needle seats widely recognized in circle-track racing, street rod, and vintage engine restoration markets. These extensions integrate seamlessly into existing Quick Fuel jetting strategies and are compatible with standard 1/4-32 threaded carburetor designs across hot rod and classic automotive platforms.
