OE: 1105100AED61 Fuel Pre-Filter for GWM H9 Diesel | GWM

The OE: 1105100AED61 fuel pre-filter is designed for the GWM H9 diesel, a body-on-frame SUV used in demanding conditions across multiple regions. relines.ru
It acts as the first protection stage in the diesel fuel system, removing larger contaminants and water before fuel reaches the high-pressure filter and injectors.
This pre-filter is essential for maintaining reliable torque, smooth operation, and long-term durability in off-road, towing, and mixed-use driving.

Compatibility

The pre-filter fits the Haval H9 first-generation facelift diesel models, typically from 2017 onward, equipped with the 2.0-liter turbo diesel engine used in markets such as Russia and other export regions. relines.ru
It is installed within the engine bay fuel circuit and works together with the main diesel filter element.
The unit is suitable for vehicles operating in cold climates, dusty environments, and regions where diesel quality can fluctuate.

Filtration / Material / Mechanical Design

The assembly uses a multi-stage diesel filtration medium that captures coarse particles and separates water from the fuel.
A robust metal housing withstands vibration, pressure pulses, and thermal cycling typical of ladder-frame SUVs driven off-road.
Corrosion-resistant internal components help maintain sealing performance when exposed to moisture and varying diesel formulations.
OE-spec ports and bracket dimensions provide a direct fit to the H9 fuel line layout, allowing quick replacement during service.
The design reduces the load on the main fuel filter, helping it focus on fine filtration and extending injector life.

Flow Stability and Engine Protection

By removing water and larger debris early, the pre-filter protects the high-pressure pump and rail system from cavitation and scoring.
Stable pre-filtration helps maintain consistent fuel pressure during acceleration, hill climbs, and low-speed off-road maneuvers.
Clean diesel flow supports smoother cold starts and reduces the risk of power loss caused by restricted filters.
The component is an important part of keeping the H9 diesel engine efficient and reliable over high mileage use.

Maintenance Replacement (Interval)

Haval maintenance guides and general fuel-filter recommendations for diesel engines indicate that diesel fuel filters and pre-filters are typically replaced between 20,000 and 30,000 km, or about once a year, with shorter intervals advised in regions with poor diesel quality. startmycar.com+1
For severe conditions, a conservative practice is to inspect at each service and replace the pre-filter around 20,000 km, or earlier if contamination or water accumulation is detected.
