Fuel Injector O-Ring Kit replacement Motorcraft CM-4717

Fuel Injector O-Ring Kit replacement for Motorcraft CM-4717

A quality alternative for fuel system maintenance

This repair kit is a high-quality replacement for the original Motorcraft CM-4717 set (Ford engineering number F0PZ-9229-A). The kit is designed for car owners and specialists who need a reliable solution for sealing fuel injectors without overpaying for the brand. The kit fully matches the fitting dimensions and physico-chemical properties of the original seals, ensuring a tight fit of the injector in the fuel rail and intake manifold. Timely installation of new rings prevents gasoline leaks and air intake, restoring engine stability.

Industrial standard materials

The sealing rings are made of high-tech fluoroelastomer (Viton/FKM). This material is specifically chosen for operation in the aggressive environment of the under-hood space. Unlike regular rubber, Viton rings have exceptional resistance to modern types of fuel with additives, ethanol, and motor oils. The rings maintain elasticity at extreme temperatures (up to +200°C) and do not degrade with prolonged contact with aggressive chemicals, ensuring system tightness throughout the service interval.

Versatility and wide compatibility

The kit is designed as a universal solution for most Ford distributed fuel injection systems (EFI/MPFI). The ring sizes (standard 7.5 x 3.5 mm) fit the most common types of injectors, including Bosch EV1, EV6, and EV14. The set of 8 pieces is intended for complete servicing of 4 injectors (two rings per injector: upper for the rail and lower for the manifold). For V8 engines (8 injectors), it is recommended to purchase two kits simultaneously.
