The OE: 1111402AED61 fuel filter assembly is the primary fine filtration unit for Haval H9 diesel models, designed to protect the common-rail injection system.
It removes small contaminants and moisture before fuel reaches the high-pressure pump and injectors.
This filter supports smooth combustion, predictable torque delivery, and steady performance across mixed driving environments.
Its design provides reliable operation for long-distance travel, light off-road use, and daily driving.
Compatibility
This fuel filter assembly fits Haval H9 diesel vehicles equipped with the 2.0-liter turbo diesel engine used in export markets.
It belongs to the AED-series fine-filtration family and works as the second stage in the H9 diesel fuel system.
The filter pairs with the XED-series pre-filter to ensure clean and stable fuel delivery.
Its connector layout and housing dimensions match OE specifications for direct installation.
The unit performs reliably in regions where fuel quality varies between stations and supply chains.
Filtration / Material / Mechanical Design
The filter features a multi-layer synthetic medium that captures fine particles without limiting flow.
Its metal housing ensures durability under pressure changes and temperature cycles.
Internal water-separation elements help reduce moisture content in the fuel path.
OE-grade sealing interfaces support stable pressure and prevent air intrusion.
The assembly is built to handle dusty roads, warm climates, and extended driving hours typical for H9 users.
Flow Stability & Engine Protection
Clean filtration improves injector spray precision and supports smooth combustion.
The filter assists with reliable cold starts and stable idling by keeping water and debris out of the high-pressure system.
Stable fuel flow reduces stress on the high-pressure pump during towing or steep climbs.
By maintaining fuel purity, the assembly helps protect the entire common-rail circuit over long service life.

Maintenance Replacement (Official Interval)
The recommended replacement interval for H9 diesel is 20,000 km.
A shorter interval of 10,000–15,000 km is recommended when operating in regions with inconsistent diesel quality.
Technicians should inspect for moisture or debris during scheduled servicing.
