Fuel Line Pressure Release Procedure

FUEL LINE PRESSURE RELEASE PROCEDURE
1. Close the fuel control valves on all cylinder(s) by turning the valves completely clockwise.

2. Ensure the manual shut-off valve is in the open position. The valve is open when the handle is parallel with the fuel tubes.

3. Start or attempt to start the engine. If the engine starts, let it run until it runs out of fuel. Attempt to restart the engine by cranking for 6 seconds.

4. Pausing 10 seconds between attempts, repeat step 3 two more times.

5. If the check valve or fuel fill receptacle is to be serviced, slowly loosen the inlet side of the fuel fill tube fitting at the check valve until fuel has purged.

WARNING: THE FUEL CYLINDERS STILL CONTAIN HIGH-PRESSURE FUEL.
