GENUINE NISSAN DIESEL FUEL FILTER TO WATER SENSOR O RING SEAL (various models)
This is the O ring seal on the bottom of the spin on fuel filter which seals the fuel sensor. It suits many Nissan models including ALL GU Y61 Patrol diesels except CRD engines, D22 Navara diesels, Most D40 Navara and R51 Pathfinder diesels along with a number of older models.
It is common to crack these when replacing the sensor or the filter and they do not come with the filter.
