Gas Fuel Differential Pressure (High)
- Excessive fuel supply pressure
- Leaks in the piping after the fuel metering valve
Check the Fuel Supply Pressure
Check the pressure of the fuel supply to the fuel metering valve for high pressure. The maximum allowable pressure to the fuel metering valve is
Adjust the gas pressure regulator in order to achieve the correct pressure.
If the gas pressure regulator cannot be adjusted to the correct setting, repair the regulator or replace the regulator.
Use a gas detector to check for leaks in the piping between the outlet of the fuel metering valve and the turbocharger compressor.
Repair the piping, if necessary.
