What must be done if the pressure gauge in a fuel system reads unusually high?

If the pressure gauge in a fuel system reads unusually high, it is essential to inspect the system for malfunctions and relieve pressure safely before resuming operations. High pressure readings can indicate potential issues such as blockages, leaks, or equipment failures that could pose serious safety risks. Addressing the pressure anomaly promptly helps prevent accidents, equipment damage, or hazardous situations, particularly when dealing with fuels like LPG or CNG, which are highly flammable.

Safely relieving the pressure allows technicians to investigate and resolve any underlying problems, ensuring that the system operates within safe parameters. This approach prioritizes safety and operational integrity, making it a critical step in fuel system management.
