Maintain reliable fuel delivery and engine performance with this Genuine Nissan Injector Pipe No.4, designed specifically for Nissan Patrol GQ and GU models fitted with the TD42 engine. This OEM injector pipe provides a precise, leak-free connection between the injector and fuel system, helping ensure consistent fuel pressure and smooth combustion—critical for diesel performance and longevity.

Over time, injector pipes can loosen, corrode, crack, or develop leaks due to vibration, heat cycles, and age. A compromised injector pipe may lead to poor engine performance, rough idling, hard starting, increased smoke, or reduced fuel efficiency. Installing a genuine replacement restores correct fuel flow and supports optimal engine operation.
