Which term describes the inner casing where fuel is held?

• A. Casing
• B. Volute
• C. Impeller
• D. Priming

Answer: (B)

The inner casing around the rotating component is called the volute. It wraps around the impeller and collects the fluid as it’s pushed outward, using its spiral, expanding shape to slow the flow and convert velocity into pressure, guiding fuel toward the discharge path. This specific housing is what distinguishes the volute from the general outer casing, the impeller itself, or the priming process.
