Product Description
The genuine OEM NISSAN fuel filter cover and manual primer pump unit with part number 16401-VB20A is an essential functional component of the diesel fuel supply system. The component serves to receive and secure the fuel filter cartridge, as well as to manually prime and bleed the fuel feed circuit following a filter replacement, routine maintenance, or running out of fuel.
The integrated hand pump and internal check valve maintain system pressure and prevent fuel from draining back into the fuel tank when the engine is off. Failure of this unit (such as a torn diaphragm, loss of sealing, or worn check valve) can cause air to enter the diesel system, resulting in starting difficulties, engine hesitation, or complete stalling.
