How can deposits in fuel tanks affect the aircraft's performance?

Deposits in fuel tanks can significantly affect the aircraft's performance primarily by blocking fuel flow. As fuel passes through the tank and associated fuel lines, deposits can accumulate, leading to restrictions. This blockage can impede the fuel system's ability to deliver the necessary fuel to the engines efficiently. When fuel flow is obstructed, it can result in uneven fuel supply, reduced power output, and even engine performance issues such as stalling or loss of power. Ensuring that fuel systems are clean and free from contaminants is essential for optimal engine performance and overall aircraft safety. This highlights the critical impact of deposits on the efficacy of fuel delivery systems within aircraft.
