Final answer:
Keeping the nozzle in contact with a tank or fill opening prevents spills, ensures accurate measurement, and prevents static electricity buildup. Contact between the nozzle and the tank or fill opening helps to discharge any static electricity that may build up during the fueling process.
Step-by-step explanation:
Keeping the nozzle of a fuel hose in contact with a tank or fill opening is important for a few reasons: To prevent spills or leaks: When the nozzle is in contact with the tank or fill opening, it forms a seal that helps prevent fuel from coming out of the tank. This reduces the risk of fuel spills and environmental contamination. ensure accurate measurement: Some fuel pumps are equipped with sensors that only allow fuel to be dispensed when the nozzle is properly inserted into the tank or fill opening.
To ensure accurate measurement: Some fuel pumps are equipped with sensors that only allow fuel to be dispensed when the nozzle is properly inserted into the tank or fill opening. This ensures that the correct amount of fuel is measured and dispensed. To prevent static electricity buildup: Contact between the nozzle and the tank or fill opening helps to discharge any static electricity that may build up during the fueling process. This reduces the risk of sparks that could potentially ignite fuel vapors.
