The OE: 1111400AED61 fuel filter is the main fine filtration element for Haval H9 diesel models, protecting the high-pressure common-rail system from fine particles and moisture.
It works as the second stage in the H9 diesel fuel circuit, ensuring that fuel entering the high-pressure pump maintains the purity required for smooth and consistent combustion.
This filter supports the SUV’s performance in daily driving, long-distance travel, and light off-road use.
Compatibility
This filter fits 2017–present Haval H9 diesel vehicles powered by the 2.0-liter turbo diesel engine used across multiple export markets.
It belongs to the AED fuel-system family, which is designed specifically for the H9’s ladder-frame platform.
The filter works in tandem with the XED-series pre-filter, forming a complete two-stage diesel filtration system.
Its housing and connector layout match the original installation points, allowing direct replacement during routine maintenance.
Filtration / Material / Mechanical Design
The filter uses a high-density multi-layer synthetic medium capable of capturing small particles before they reach the injectors.
Its durable aluminum housing resists pressure changes during acceleration and temperature shifts.
Internal water-separation features help reduce moisture content, supporting consistent injection performance.
OE-spec sealing surfaces offer stable fitment and reliable fuel routing through the high-pressure circuit.
The filter maintains flow stability even when the vehicle is used in warm climates or during long driving cycles.
Flow Stability & Engine Protection
Clean filtration supports accurate injector spray patterns and smooth combustion.
The filter helps maintain cold-start reliability by keeping water and fine debris away from the high-pressure pump.
Stable fuel flow contributes to predictable torque output and smooth throttle response.
The component also lowers the load on other fuel-system parts, promoting consistent engine behavior over long service life.

Maintenance Replacement (Official Interval)
H9 diesel service documentation recommends replacing the fine fuel filter every 20,000 km.
In regions with inconsistent diesel quality, a 10,000–15,000 km interval is advised.
Technicians should check for moisture and debris during each routine inspection.
