This is a Genuine Nissan fuel filter water sensor, a critical component for all diesel Nissan Patrol Y61 GU models with TD42 and RD28 engines. Located in the engine bay and screwed into the bottom of the fuel filter assembly, this sensor's job is to detect any water that has contaminated your diesel fuel and trigger the warning light on your dashboard, giving you an early alert before catastrophic engine damage can occur.
A faulty or failed water sensor must be replaced immediately. Common signs of failure include the 'water in fuel' warning light staying on permanently, or worse, not activating when it should. Installing a Genuine Nissan sensor is the only way to guarantee correct operation and protect your engine. As a direct-fit component, replacement is straightforward and can be handled by a confident home mechanic or any workshop.
When replacing the water sensor, it is a good opportunity to also replace the fuel filter and any related O-rings or seals.
