If the dispenser installation is primarily used to fill larger, vehicle mounted mobile, or motor fuel tanks at a filling station or fleet service center, a ______ pump should be considered to reduce filling time and minimize operator waiting that could contribute to lack of attention during the filling operation.

• A. Small
• B. Medium
• C. Large
• D. Ultra Large

Answer: (C)

When you’re filling larger vehicle-mounted or fleet tanks, you want a pump that can move propane quickly. A large pump delivers a higher flow rate, which shortens the fill time and reduces how long the operator has to stand at the station. That helps keep the operator focused on the task and lowers the chance of distraction during filling. Slower pumps would take longer for big fills, increasing wait times and opportunities for attention to drift. Just be sure the rest of the system—hoses, regulators, and safety controls—can safely handle the higher flow.
