Parts for your 2009 Nissan Dualis-Fuel pump

2009 Nissan Dualis (J10) fuel pump — purpose, service and replacement

Based on technical references including the Nissan Electronic Service Manual (ESM) for the J10 platform (Dualis/Qashqai, 2007–2013), the Nissan FAST parts catalogue for J10, and common component listings from major suppliers, the 2009 Nissan Dualis is fitted with a fuel pump. Petrol variants (e.g., MR20DE) use an electric in‑tank pump module, while diesel variants use a high‑pressure injection pump and, depending on the exact engine and market, may also have a low‑pressure in‑tank lift pump or rely on the high‑pressure pump to draw fuel through the filter.

On the petrol Dualis, the in‑tank electric pump sits inside a combined module that also carries the level sender, strainer and pressure regulation hardware. Its job is simple but critical: supply clean fuel at the correct pressure to the rail so the injectors can meter it precisely. When it gets tired, the engine can feel flat, hesitate, or take ages to start.
