The part number P31H-13-ZE0 is a Genuine OEM Fuel Filter Body manufactured by Mazda for the CX-3 crossover. The official description is "BODY, FUEL FILTER" or "Housing".
This part is crucial because, in modern Mazda SKYACTIV-G gasoline engines, the filtration system is highly integrated and modular:
In-Tank Module: This component is the main structural plastic housing of the fuel pump/meter unit that sits submerged inside the fuel tank. The filter itself is a large-capacity element (often PE01-13-ZE1) that is contained within this body, alongside the electric fuel pump motor and the high-pressure regulator.
SkyActiv Specificity: This part is designed for the SKYACTIV-G 2.0L engine used in the CX-3 (DK chassis). This system requires extremely precise and clean fuel delivery to operate the high-pressure direct injection (GDI) system, making the integrity of this housing and the filter within it vital for engine performance and reliability.
Genuine Quality: As a GENUINE PART, using the P31H-13-ZE0 guarantees correct material composition, accurate dimensional fit, and proper sealing within the fuel tank and surrounding module components.
Fitment Assurance: The part number P31H-13-ZE0 is verified as the correct genuine Fuel Filter Body/Housing for the Mazda CX-3 (DK Chassis) 2.0L SKYACTIV-G Gasoline FWD models (2016–2021).
