Turn off the engine and relieve fuel system pressure before starting work.

Use clean rags and safety gloves; disconnect inlet and outlet fuel lines using appropriate line wrenches.
Remove mounting bolt(s) securing the old WG9716550107 filter.
Drain residual fuel into a proper container.
Lubricate the new filter’s O-ring lightly with clean diesel or engine oil.
Install the new filter and hand-tighten — follow torque specs (typically 25–30 Nm).
Bleed air from the fuel system using the manual priming pump or electric primer.
Start the engine and check for leaks at connections under running conditions.
