Generator starts then stalls under load and displays LOW FUEL PRESSURE or FUEL SUPPLY fault.

Safety first: Turn the generator OFF and shut off the gas supply before loosening any fittings. Do not smoke or use open flames near fuel.

• Verify gas valves: Confirm all manual gas shutoff valves are fully open.
• Inspect regulator: Check the Centurion primary fuel regulator for frost buildup, oil contamination, or physical damage.
• Check for kinks: Inspect the flexible gas hose from the regulator to the engine for kinks or crushing.
• Contact gas provider: For natural gas systems, have the utility verify supply pressure under load. For LP, ensure tank is not near empty and that the tank regulator is functioning.

When to call a technician: A licensed technician should measure fuel pressure at the generator inlet during operation and replace the Centurion fuel regulator or piping if out of specification.
