Does the jerky movement of the fuel nozzle cause fuel loss. Reasons for fuel loss: After testing by professionals, it has been proven that the repeated tightening and releasing of the fuel nozzle can cause gasoline backflow, which indeed results in reduced fuel delivery. Although this mechanism is designed to prevent overflow during refueling, it does lead to decreased fuel quantity. This occurs because frequent on-off operation of the throttle causes data recording lag in the nozzle's switch valve - meaning the meter starts counting before fuel actually flows out. After shutting off the nozzle, un-dispensed fuel begins flowing backward, creating significant measurement errors. Definition of fuel nozzle: The fuel nozzle is the terminal output device of gas station dispensers that interfaces with vehicle fuel tanks. The most commonly used types are self-sealing nozzles and composite nozzles.
