OE: 1111400XEDA2 Fuel Filter for GWM Cannon Diesel | Great Wall

The OE: 1111400XEDA2 fuel filter is the primary fine filtration unit for the GWM Cannon diesel platform, supporting the fuel requirements of modern common-rail systems.
It captures fine particles and moisture before fuel reaches the high-pressure pump and injectors.
This filter helps maintain steady torque output, smooth acceleration, and reliable performance across daily driving and work environments.
The design supports the practical needs of utility drivers, commercial users, and owners who expect consistent operation from their pickup.

Compatibility

This filter fits GWM Cannon (金刚炮 / King Kong Cannon) diesel models, which share architecture with the global Poer diesel lineup.
It supports engines such as:

• GW4D20M diesel engine

• GW4D20D diesel engine

These engines rely on stable fuel supply to maintain injection accuracy.
The filter works within the Cannon’s two-stage fuel system, operating as the final stage before the high-pressure pump.
Its housing and connector layout follow OE specifications for direct replacement.
It performs reliably in markets where diesel quality can vary, supporting global commercial use.

Filtration / Material / Mechanical Design

The filter features a multi-layer synthetic medium designed to capture fine contaminants without restricting flow.
Its metal housing provides durability under pressure changes and temperature cycles.
Internal water-separation structures reduce moisture levels in the fuel.
OE-grade seals offer stable installation and maintain pressure integrity within the fuel line.
The filter performs well in mixed urban, highway, and dusty rural environments that Cannon users often encounter.

Flow Stability & Engine Protection

Clean filtration supports correct injector spray patterns and predictable torque delivery.
The filter helps maintain smooth idle and dependable cold-start performance.
Stable fuel flow lowers the strain on the high-pressure pump during heavy-duty operation.
With improved protection from fine contaminants, the filter supports long-term reliability for the diesel injection system.
