Maintain correct fuel system pressure and reliable injector return flow with this Genuine Nissan Injector Fuel Return Rail Bleed Off, designed specifically for Nissan Patrol GU Y61 models fitted with the ZD30 diesel engine. This OEM rail assembly sits across the injectors and regulates fuel return and bleed-off, ensuring smooth operation of the high-pressure fuel system.

Over time, injector return rails can become brittle, cracked, or damaged during injector removal or fuel system servicing. A failing rail may cause fuel leaks, air ingress, hard starting, rough idle, or inconsistent engine performance — all of which can impact drivability and fuel system reliability.

Manufactured to genuine Nissan specifications, this direct-fit replacement restores correct fuel return routing, secure injector connections, and long-term durability in demanding touring, towing, and off-road conditions.
