(6) Gas Shutoff Valve (GSOV)
(7) Gas pressure sensor
(8) Gas line
(9) Fuel control valve
Turn off the main gas valve.
De-energize the GSOV.
Slowly remove gas pressure sensor (7) from gas line (8).
Install a fitting into gas line (8). Connect the 1U-5470 Engine Pressure Gp to the fitting. Refer to Illustration 1. Test Procedure - Fuel Pressure to Control Valve
Do not allow dirt to enter the fuel system. Thoroughly clean the area around a fuel system component that will be disconnected. Fit a suitable cover over disconnected fuel system component.
Open the main gas valve.
Energize the GSOV.
Check the engine gas pressure to the fuel control valve. If, the pressure is not 10.3 to 24.1 kPa (1.5 to 3.5 psig) refer to Adjustment Procedure - Fuel Pressure to Fuel Control Valve. Adjustment Procedure - Fuel Pressure to Fuel Control Valve

(10) Bolt
(11) Cover
Remove cover (11), and install the correct tools, from the 8T-5160 Gas Regulator Setting Tool, for pressure setting adjustment.
Adjust bolt (10) to achieve desired fuel pressure to the fuel control valve.
After desired pressure is reached, install cap (11).
