Quick Fuel Technology Gas Main Jet Thread Jets

Quick Fuel Technology Gas Main Jets are threaded carburetor main jets for gasoline-fueled carburetors. They let you fine-tune high-throttle fuel delivery and air/fuel ratio. Main jets are also called carburetor metering jets or thread-in jets. Changing them is one of the most common ways to calibrate a carburetor after engine modifications, or for a different altitude or weather.

Key Features:

• Precision manufactured: Made to an exacting standard that meets or exceeds O.E.M. specifications, so flow is predictable and consistent from jet to jet.
• Gasoline-specific design: Gas jets use a standard 1/4-inch thread size in most applications. Quick Fuel's alcohol jets are a separate product line.
• Stamped for identification: Each jet is marked with its jet number, so you can quickly confirm what is installed in the carburetor.
• Wide range of jet numbers: Many jet numbers are available, which allows small, incremental tuning changes.
• Made in the USA: Built by Quick Fuel Technology, a well-known maker of performance carburetors and carburetor tuning components.
• Warranty: Backed by the manufacturer's limited 90-day warranty.

Quick Fuel jet numbers correlate to O.E.M. main jet flow rates. The jets are sized by actual flow, so the stated hole size is a reference only. Choose the jet number that matches your tuning goals, then confirm the result with spark plug readings or an air/fuel ratio gauge.
