Holley Mdl 4150 750 CFM Double Pumper Carburetor

Engineered as a performance upgrade for hot street machines and race ready builds, this Holley Double Pumper blends classic American engineering with modern fuel delivery. The aluminum body, available in gold dichromate or tumble polished finishes, adds a premium look to your engine bay while delivering a robust fuel path for spirited driving.

Key design benefits

• Optimized street/strip calibration that works out of the box, helping you get to the track or the road quickly.
• Manual choke (cable driven and hand operated) for precise cold weather starts and consistent warmups.
• Mechanical secondaries that respond to throttle input with a smooth, confident surge.
• Dual accelerator pumps supply additional fuel during the initial pull, supporting rapid throttle response.
• Dual feed fuel inlets provide ample, constant fuel delivery for sustained performance.

Real world use scenarios include hot street cruising, weekend drag days, or lightweight builds where fast throttle response matters. The combination of dual pumps and dual feeds is designed to maintain fuel flow during high demand moments, while the manual choke gives you control over cold starts.

Finish and fit

The aluminum construction paired with your choice of gold dichromate or tumble polished finishes ensures both durability and a striking look under the hood. This carburetor suits lightweight builds where a manual transmission or high stall automatic is part of the setup, and it is designed for straightforward calibration and reliable operation for enthusiasts who value hands on tuning.

Note that outcomes can vary based on engine condition, gearing, and tuning. This product is a performance upgrade option and is not a guaranteed result in every vehicle.
