• For safe relief of residual fuel pressure, ensure the engine has stopped for at least 30 seconds before inspection.

Releasing Residual Pressure from Fuel System

The fuel system generates pressure within both the low-pressure and high-pressure circuits while the engine operates.

• The pressure in both circuits automatically reduces to a safe level 30 seconds after engine shutdown.
• Prior to inspecting the fuel system or removing parts, ensure all residual pressure is fully released.
• Always wait at least 30 seconds post engine shut-off before commencing work on the fuel system to ensure safety.
