Installation Notes

Clean the injector bore and sealing surfaces before installation, and inspect the injector body for wear or damage that could affect seal retention. Match the O-ring and seal sizes to the injector location being serviced, and lubricate seals with approved fuel-system lubricant during assembly. Verify proper seating before reassembly and fuel system pressurization.
