Jet Assortment Kit - #70 to #80

The Jet Assortment Kit - #70 to #80 from Quick Fuel Technology is an essential tuning tool for carburetor enthusiasts and performance mechanics who demand precision fuel metering. Whether you're dialing in a street machine, bracket racer, or vintage restoration, this brass jet assortment covers a critical range of orifice sizes that control fuel flow through the main and idle circuits. This kit eliminates the need to source individual jets across multiple suppliers and ensures you have the exact sizing options required for proper carburetor calibration.

Constructed from solid brass, each jet in the Jet Assortment Kit features precise orifice sizing stamped with its corresponding number for quick identification during tuning sessions. The #70 through #80 range addresses mid-range to richer fuel mixtures, making this kit ideal for engines running boost, large displacement builds, or high-altitude compensations. Quick Fuel Technology's jets are manufactured to tight tolerances—even a single jet size difference can shift air-fuel ratio by nearly 1 percent—ensuring repeatable results when optimizing carburetor performance. The included jet holder organizes each size and protects the precision orifices from damage during storage and transport.

Carburetor tuning professionals, engine builders, and serious DIY mechanics benefit most from keeping this assortment on hand for rapid jetting changes at the track, dyno, or shop bench. The kit is compatible with Quick Fuel carburetors and most aftermarket four-barrel designs that accept standard 0.031-inch jet orifices. Installation requires only a jet wrench or appropriately-sized screwdriver; always verify your carburetor's jet seat depth and fuel bowl design before swapping jets to ensure proper float bowl sealing and fuel delivery.
