Parts for your 2001 Nissan Serena-Fuel pump

2001 Nissan Serena fuel pump — what it does, where it lives, and when to sort it

Based on technical sources, a fuel pump absolutely is relevant to the 2001 Nissan Serena. The Nissan C24 Serena Factory Service Manual (EC and FL sections) specifies an in-tank electric fuel pump module for petrol QR20DE models, and a low-pressure feed plus a high-pressure supply/injection pump for YD22DDTi diesel variants. Nissan’s FAST parts catalogue lists the fuel pump module (17040‑xxxxx series) for C24 petrol versions, and service literature for the YD22DDTi details the engine-mounted high-pressure pump with a dedicated supply path. In short: every 2001 Serena runs a fuel pump system suited to its engine.

On petrol Serenas, the in-tank electric pump keeps a steady flow and pressure to the injectors, ensuring smooth starts, clean acceleration, and decent economy. Diesel models rely on a lift/supply arrangement and a high-pressure pump to feed the common-rail or direct-injection system with precision. If the pump can’t keep up, the Serena will feel flat, hard-start, or stall under load.

As part of regular servicing, it’s wise to think of the fuel pump as a “fit-and-forget” item that still appreciates clean fuel and a healthy filter. Keeping the fuel filter fresh (per the Nissan schedule) protects the pump from strain. Running the tank low all the time can overheat an in-tank pump
