Parts for your 2017 Nissan Serena-Fuel pump

2017 Nissan Serena fuel pump — what it does and how to look after it

Yes, the 2017 Nissan Serena (C27) uses a fuel pump. Technical sources including the Nissan C27 Serena Service Manual (FL — Fuel System, EM — MR20DD and EM — HR12DE e-POWER sections) and the Nissan Electronic Parts Catalogue for C27 list an in‑tank electric fuel pump module (often combined with the level sender). On MR20DD direct‑injection models there’s also a cam‑driven high‑pressure pump on the engine that’s fed by the in‑tank pump. e‑POWER variants still use an in‑tank electric fuel pump to supply the generator engine. Those references confirm the pump is very much part of the 2017 Serena’s setup.

In day‑to‑day terms, the Serena’s fuel pump pushes petrol from the tank to the engine at the right pressure for clean starts, smooth idle and decent pull up hills. On the MR20DD, the in‑tank pump provides a steady low‑pressure feed, while the engine‑mounted pump steps pressure up for the direct injectors. The e‑POWER’s 1.2‑litre engine is port‑injected, so the single in‑tank pump handles delivery.

There’s no fixed replacement interval, but the pump is worth a look whenever servicing brings up hard starting, hesitation, or a whine from the tank area. A pro with a scan tool can check fuel pressure, trims and any related fault codes to confirm what’s going on.

• Common warning signs: extended cranking, surging on acceleration, loss of power at motorway speeds, louder-than-usual priming noise, or faults such as low fuel pressure.
• Good habits: avoid regularly running the tank near empty (the pump relies on fuel for cooling), use quality petrol, and keep the tank and cap clean to reduce debris and moisture.

When replacement is needed, it’s typically the entire in‑tank module. The job involves depressurising the system, disconnecting the battery, lifting the rear seat base to access the service cover, removing the locking ring, swapping the module, fitting a new seal, then re‑torquing the ring and leak‑testing. For MR20DD models, don’t forget there’s also a high‑pressure pump on the engine that can be diagnosed separately if rail pressure is off.

Most C27s have the filter integrated into the pump module, so there’s nothing to “change” at routine intervals. During major services, it’s smart to listen for a clean, brief prime at key‑on, check for any fuel smell around the access cover, and verify pressures if drivability isn’t quite right. Using a quality OEM‑equivalent module will help keep the Serena happy for the long haul, well past the 150,000–250,000 km many pumps comfortably reach.

• Where is the fuel pump on a 2017 Nissan Serena?
  It’s an electric in‑tank module beneath the rear seat area, accessed via a service cover. On MR20DD engines there’s also a separate high‑pressure pump on the engine.
• Does the 2017 Serena have more than one fuel pump?
  MR20DD direct‑injection models have the in‑tank low‑pressure pump plus a cam‑driven high‑pressure pump. e‑POWER variants use the single in‑tank electric pump for their generator engine.
• Can the fuel filter be replaced on its own?
  On most C27 Serenas the filter is built into the in‑tank pump module, so it’s replaced with the module rather than serviced separately.
