A-Premium 2-Barrel Carburetor 2100/A800 Replacement for Ford Jeep Mercury — Direct-Fit, Pre-Set Jets

The A-Premium 2-barrel carburetor 2100/A800 is a direct-fit replacement carb designed to restore throttle response and reliable fuel-air metering for classic Ford, Jeep Wagoneer and Mercury vehicles.

Built to match the form and function of original two-barrel designs, this A-Premium carburetor aims to provide consistent idle characteristics, smooth part-throttle power and straightforward installation for restorations and maintenance projects. It replaces OE 2100/A800-style units used on many 1960s–1970s V8 and V6 applications, and ships with a one-year unlimited-mileage guarantee for added confidence.

Which vehicles and engines will this carburetor fit?

This carburetor fits a range of classic American trucks, muscle cars and SUVs that originally used the 2100/A800-style two-barrel. It covers multiple displacements and model years commonly needing the same mounting pattern and throttle linkage.

• Ford F100/F250/F350 (1964–1978/1979): 289, 302, 351 cubic-inch engines
• Mustang (1968–1973): 289, 302, 351 Ci V8 options
• Jeep Wagoneer (1964–1978): 360 Ci (5.9L) applications
• Mercury Comet (1964–1982): compatible 289, 302, 351 Ci engines

How does this carburetor improve driveability and fuel metering?

The A-Premium unit restores correct air-fuel ratios across idle and part-throttle conditions thanks to calibrated jets, an appropriate float setting and matched venturi sizing. That improves throttle response and reduces hunting when compared to worn or plugged original carburetors.

• Pre-set float and jets for predictable idle and transition behavior
• Two-barrel venturi arrangement optimized for mid-range torque
• Standard throttle linkage and vacuum ports for direct fitment

What do I need to install it and how straightforward is the swap?

Installation is generally straightforward for anyone comfortable with basic engine service. The carburetor uses the same mounting bolt pattern and common throttle and choke connections found on 2100/A800-style units, allowing a bolt-on replacement in most cases.

• Typically requires standard hand tools and a clean intake manifold surface
• Reconnect fuel line, throttle linkage, choke and vacuum hoses per original routing
• Check float level and idle mixture after installation for best results

What does A-Premium’s warranty and support cover?

A-Premium includes a one-year unlimited-mileage guarantee, showing confidence in manufacturing and fitment. That warranty covers defects in materials and workmanship so you can install the part with reduced risk compared to non-guaranteed alternatives.

• One-year unlimited-mileage warranty from A-Premium
• Manufactured to match 2100/A800 reference dimensions and function
• Customer support available for fitment and installation questions

Who is this for: This carburetor is intended for restorers, classic truck and muscle-car owners, and home mechanics who need a direct-replacement two-barrel unit for mid-1960s through late-1970s Ford trucks, early Mustangs, Jeep Wagoneers and compatible Mercury models. It’s ideal when the original carburetor is worn, leaking, or no longer providing stable idle and throttle response, but you want a straightforward, period-correct repair without modifying the intake or throttle assemblies.
