A booster or auxiliary pump is generally fitted in case of an ________ failure.

Explanation:
A booster or auxiliary pump is used to ensure fuel pressure is maintained if the main engine-driven pump stops delivering fuel. The engine-driven pump provides the primary high-pressure flow needed during normal operation, but if it fails, the engine would lose fuel pressure and stop. The booster pump (often electric) serves as a secondary source to keep fuel moving to the engine, allowing starting and continued operation until the primary pump issue is resolved. Filtration or tank size doesn’t address the immediate need for pressure continuity, and the booster’s role is specifically to back up the primary pump's failure scenario.
