Which type of fuel-boost pump is responsible for separating air and vapor from the fuel before it enters the carburetor line?

The centrifugal-type pump is designed for effective fuel transfer and is particularly adept at handling liquids while minimizing the presence of air and vapor. In a fuel system, this type of pump creates a flow of fuel that allows it to separate air and vapor from the liquid fuel. It achieves this by utilizing the principle of centrifugal force, which forces the fuel outwards and helps to settle any vapor or air bubbles, ensuring that the fuel delivered to the carburetor line is as free from these undesirable elements as possible.

This separation process is critical because air and vapor can disrupt the fuel-air mixture necessary for optimal engine performance. Ensuring that only liquid fuel reaches the carburetor enhances combustion efficiency and engine reliability. The centrifugal pump's design and operation make it particularly effective in this role within an aircraft's fuel system.
