Maintain a leak-free fuel system with this Genuine Nissan Lower Injector O-Ring, designed to suit Nissan Patrol GU Y61 models fitted with the TB45 petrol engine. This OEM O-ring is fitted to the lower section of the fuel injector, creating a secure seal where the injector meets the intake manifold. It helps maintain correct fuel pressure, prevents fuel leaks, and supports efficient engine performance.

Over time, the injector O-ring can harden, shrink, crack, or deteriorate due to constant heat exposure, fuel contact, engine vibration, and age. A worn or damaged seal can allow fuel leaks, rough idling, reduced fuel economy, poor engine performance, and fuel odours around the engine bay. Replacing the O-ring with a Genuine Nissan component restores the factory seal and helps ensure reliable fuel delivery and engine operation.
