This component is mounted over the fuel injector and functions as both a locating bearing and vibration-damping O-ring. It ensures the injector is correctly positioned while reducing movement and absorbing vibration within the fuel system.
Manufactured from durable rubber material, this locating bush is engineered to withstand fuel system conditions, heat, and long-term use while maintaining flexibility and sealing performance.
A direct replacement part, this injector locating inner bush is essential for maintaining proper injector alignment, reducing vibration, and ensuring reliable fuel delivery.
Key Features
• Direct replacement fuel injector inner locating bush / O-ring
• Suitable for Porsche 928S (M28.19 / M28.20 / M28.21 / M28.22)
• Also used in various compatible vehicle applications (including Mercedes)
• Provides injector positioning and vibration damping
• Durable rubber construction for long-term performance
• OEM-style fit and function
Function and Purpose
This locating bush acts as both a positioning guide and vibration damper for the fuel injector.
It helps to:
• Secure the injector in its correct position
• Absorb vibration within the fuel system
• Improve sealing and stability
• Support consistent fuel delivery and injector performance
Why Replace Your Injector Locating Bush
Over time, rubber sealing and damping components can degrade.
Common issues include:
• Hardened or cracked rubber
• Loss of elasticity and damping ability
• Poor injector seating or movement
• Fuel system vibration or instability
Replacing the locating bush restores proper injector fitment and improves overall system performance.
