The Autolite D0AF-AK 4300 4-barrel carburetor is a high-performance carburetor designed specifically for use with the 1970 Ford Mercury 428 and 429 V-8 engines. This carburetor delivers excellent fuel efficiency, increased horsepower, and improved throttle response.

The D0AF-AK 4300 carburetor features a four-barrel design with four venturi throats and four separate float bowls. Each barrel is equipped with Accu-Mixture second-generation circular-slide carburetor technology, which provides precise fuel volume control for optimal combustion in each cylinder. The meticulously crafted jets and needles deliver an accurate fuel-air mixture for smooth engine operation and improved power output.

The integrated air cleaner base provides an easy-to-access mounting location and includes an adjustable idle jet that can be fine-tuned for optimal engine performance.

Beneath the carburetor, a heavy-duty float assembly holds the fuel tightly in place. The innovative fuel feed system ensures a constant fuel supply to the engine, preventing surges or hesitations. The braided stainless steel fuel line further enhances fuel quality by minimizing the risk of fuel contamination and deterioration.

The secondary metering rods and power valves enable precise throttle response and an aggressive powerband. This carburetor also includes a vacuum secondaries system, which optimizes vacuum signal delivery for a smooth transition between idle and wide-open throttle.

The Autolite D0AF-AK 4300 carburetor is engineered to meet or exceed factory emission standards. Its smooth operation ensures a clean burning engine and minimizes exhaust emissions, making it an excellent choice for classic car enthusiasts who want to preserve the original character of their vehicles while adhering to modern environmental regulations.

The comprehensive installation kit includes all necessary hardware, ensuring a seamless integration into your vehicle. With the right tools and some basic mechanical skills, you can easily swap out your old carburetor for this high-performance Autolite unit, transforming your classic Ford Mercury into a powerful and responsive driving machine.
