The fuel system contains high-pressure fuel and exposure to high-pressure fuel can result in personal injury. Allowing the engine to sit for 15 minutes after being operated will allow the fuel system to return to a safe pressure level. Use Electronic Technician to verify that fuel system pressure and temperature have returned to a safe level before opening the system. Note: Any components that have been removed must be sealed in order to prevent contamination. Plug any orifices that are exposed after parts have been removed.
Clean the area around the high-pressure fuel line on the number two cylinder. Be sure that no dirt or debris can enter the fuel system. Fuel system components can easily be damaged by dirt and debris.

Remove the bypass line and remove the high-pressure fuel line on the number two cylinder. Refer to Disassembly and Assembly, RENR7466, for information and the disassembly and assembly of the fuel system. Install plugs and caps on any exposed orifice of the fuel system in order to prevent dirt and debris from entering. Refer to Reuse and Salvage Guideline, SEBF9109, "Handling Procedures for the Components of the Common Rail Fuel System for C175 Engines" for information on the plugs and caps that are used to cover the exposed orifices of the fuel system.

Particle analyzerNote: If a particle analyzer is available, monitor fuel system contamination.
Monitor the particle analyzer and flush the system until ISO 15/13/10 is met.
Disconnect the filter cart and the flushing connectors from the engine. Prepare the filter cart for storage.
Reassemble the fuel system after verifying that flush results are acceptable.
Start and run the engine for one to
