Parts for your 2010 Nissan Serena-Fuel pump

2010 Nissan Serena fuel pump — what it does and how to look after it

Based on Nissan’s Electronic Service Manual for the Serena C25/C26 series (Fuel System – FL section, MR20DE), the 2010 Nissan Serena runs an electronically controlled, in-tank electric fuel pump. The parts catalogue for C25/C26 models also lists a complete pump module (commonly referenced as 17040-xxxxx) with integral regulator and strainer, confirming it’s a fitted and essential component. Engine control documentation for the MR20DE further details ECU-driven pump relay control, which only applies when a high-pressure EFI pump is present. So yes, a fuel pump is absolutely relevant on a 2010 Serena.

On this model, the fuel pump sits inside the tank as a modular unit. Its job is to supply steady, high-pressure fuel to the MR20DE engine’s injectors, with pressure regulated within the module for smooth running and crisp throttle response. Because it’s an in-tank setup, it also helps cool itself with fuel and reduces pump noise.
