EMULSION TUBES

Precision Engineering for the Perfect Fuel Curve The holes drilled into an emulsion tube control the entry of air into the fuel column, effectively managing the "timing" of the main circuit. Choosing the right profile is critical for:

• Smoothing Out Transitions: The most popular profiles, such as the F11 and F7, are designed to eliminate the "flat spots" that can plague dual-carburetor setups during acceleration.

• Customized Atomization: Different hole patterns change how the fuel is aerated before it reaches the venturi. This allows you to tailor your engine’s performance to match specific camshaft profiles, displacement sizes, and intake port designs.

• Consistent Multi-Barrel Performance: Our emulsion tubes are manufactured to exacting tolerances, ensuring that every barrel of your Weber IDF or EMPI HPMX setup works in perfect harmony for a balanced and reliable engine.

Tuned for Performance and Protection Properly selected emulsion tubes do more than just improve drivability; they help protect your engine. By ensuring a consistent and well-atomized fuel mixture, you can maintain safer cylinder head temperatures and prevent the lean conditions that lead to engine damage. Whether you are building a high-revving street Beetle or a rugged off-road racer, these precision brass components are essential for a professional-grade tune.
