Maintain a clean, leak-free diesel fuel system with this Genuine Nissan Lift Pump Water Sensor O-Ring, designed for Nissan Patrol GQ Y60 and GU Y61 models across RD28, TD42, and ZD30 engines. This OEM O-ring seals the water sensor located on the fuel filter assembly, helping prevent fuel leaks and maintaining correct system pressure.

Over time, the original seal can harden, crack, or shrink due to exposure to diesel fuel, heat, and age. A worn water sensor O-ring may allow fuel seepage or air ingress into the fuel system, which can lead to hard starting, rough running, fuel odours, or inconsistent engine performance.

Manufactured to genuine Nissan specifications, this direct-fit replacement ensures reliable sealing performance, correct fitment, and long-lasting durability in harsh Australian driving conditions.
