Using a Water Column (Manometer) to Determine the Appropriate Fuel Pressure

An analog or digital manometer can be used to determine if the fuel pressure falls into the appropriate range.

Liquid Propane - 10 to 12 inches of Water Column (.36-.43 PSI)
Natural Gas - 3.5 to 7 inches of Water Column (.13-.25 PSI)

Note: Fuel pressure requirements are not determined by the generator's regulator or fuel inlet. View your generator's user manual to verify fuel pressure: How Do I Find a Copy of My Home Standby Generator Owner's Manual and Spec Sheets?

Fuel Considerations

If the fuel pressure is too low, the generator will be starved for fuel and will not start, will not run smoothly, or will not be able to support a load.
If the fuel pressure is too high, the solenoid will not open and the generator will not start.
