NOTICE
Care must be taken to ensure that fluids are contained during performance of inspection, maintenance, testing, adjusting and repair of the product. Be prepared to collect the fluid with suitable containers before opening any compartment or disassembling any component containing fluids.

Keep protective caps on the removed components until they are reinstalled. There are three service cap kits for the C175 fuel system (refer to SEBF9109). These kits will provide dealers and customers with the necessary parts for contamination control of the fuel system components during service.
