Advanced Engine Design Nitrophyl Modified Carburetor Float

The Advanced Engine Design (AED Performance) Nitrophyl Modified Carburetor Float is a center-hung performance carburetor float made for Holley 4150-style carburetors. It helps hold a consistent fuel level in the fuel bowl, which supports reliable metering and steady engine performance in racing and high-performance use.

Key Features:

• Nitrophyl construction, a closed-cell material that resists fuel absorption
• Modified design for drag race and oval track carburetor setups
• Center-hung style for Holley 4150 carburetors
• Sold individually; each float is a single carburetor float
• Made by Advanced Engine Design, a performance carburetor manufacturer

Advanced Engine Design is based in North Chesterfield, Virginia. It designs and builds racing carburetors using in-house CNC machining, flow benches and dyno testing. This float line draws on that experience and gives your carburetor a dependable, race-ready float option.
