The insulator helps absorb vibration, stabilize injector positioning, and maintain a proper seal to prevent fuel or vacuum leaks. It also ensures correct injector seating, which is critical for consistent fuel delivery and engine performance. As a heat- and fuel-exposed wear item, it is commonly replaced during injector service or fuel rail removal to maintain reliable operation in both Fairlady Z and 300ZX applications.
