About Quick Fuel Technology

“Innovators in fuel systems” is more than just a by-line. Quick Fuel Technology, since it’s inception in 1998, has grown exponentially culminating into the benchmark by which performance carburetors are measured.

The growth and success of Quick Fuel Technology is attributed to the strength and determination of its staff. All of the innovations you see on this website are the product of a team that is both experienced and involved in motorsports. We continue to develop new products so that we can stay on the forefront of innovation. Over the years, Quick Fuel Technology has made considerable strides to become a stand-alone carburetor manufacturer. This increase in efficiency and capability has allowed us to continuously upgrade our products while keeping the prices low.

In 2005, Quick Fuel Technology introduced its Super Street line of carburetors. This application-specific line catered to the enthusiast that wanted the best carburetor for the money while refusing to compromise street manners. Drawing from our race track experience we employed many features that were normally found on much pricier race carburetors, yet ours is generally half the price!

In 2009, Quick Fuel Technology launched the QFX-Series. This design incorporates significant race engineered main body upgrades. Each carburetor is individually hand-assembled and engine tested. There simply is not a better carburetor for your money.

2010 saw the introduction of two new carburetor series from QFT -

The RaceQ is the ultimate small flange drag race carburetor and packed with features that are sure to take your package to the next level. The Hot Rod series carburetor is our answer to the needs of street machines everywhere - from muscle cars to street rods, the HR Series is the most affordable and tunable carburetor on the market today.

Keeping true to our motto, we look to the future and constantly seek the next innovation. With our past experience and race-track development we continue our pursuit of horsepower and efficiency.
