Superior fuel filtration for high-pressure injection systems – The OEM FG9604550030 Fuel Filter Unit (Dx150) is engineered to remove 99.5% of water and particles down to 5 microns, protecting injectors from wear and corrosion. Designed for SINOTRUK Homan diesel engines, this spin-on filter unit ensures reliable fuel delivery. For guaranteed compatibility and performance, always choose genuine Sinotruk Homan parts.
The FG9604550030 features a high-efficiency multi-layer media with a water separator membrane and a built-in sediment bowl with a water-in-fuel sensor port, providing real-time contamination alerts.
The FG9604550030 fuel filter unit uses a three-stage filtration process: a coarse pre-filter (100 µm), a high-density cellulose/synthetic media (5 µm absolute), and a hydrophobic water separator membrane (≥99% efficiency). This ensures that only clean, dry fuel reaches the injection pump and injectors.
Unlike standard filters, this unit includes a transparent sediment bowl with a drain valve for manual water removal and a factory-fitted water-in-fuel (WIF) sensor port (sensor not included but compatible with standard M14 x 1.5 probes). The filter housing is made from corrosion-resistant anodized aluminum with a nitrile rubber seal that withstands bio-diesel blends up to B20.
The filtration capacity is rated for up to 150 L/h, sufficient for engines up to 500 hp. The low pressure drop (≤0.15 bar at nominal flow) ensures adequate fuel supply even at full load, while the built-in bypass valve (0.5 bar crack pressure) prevents fuel starvation if the filter becomes clogged.
Removes 99.5% of particles ≥5 µm, protecting common rail injectors with micron tolerances. Three-layer media for high dirt-holding capacity.
Hydrophobic screen and coalescing media remove free water to below 50 ppm. Transparent bowl allows visual inspection.
Pre-drilled M14 x 1.5 boss accepts standard water-in-fuel sensor. Connect to dashboard warning light or ECU.

The FG9604550030 incorporates a double-helix water separation channel that spins incoming fuel, forcing water droplets to coalesce on the hydrophobic screen and fall into the sediment bowl. This passive system requires no moving parts and works at all flow rates. The bowl includes a water level mark and a magnetic float (optional) for visual indication.
The filter element is pleated with a high dirt-holding capacity (65 grams of standard ISO 12103-1 A3 dust). The media is impregnated with a phenolic resin that resists collapse under pressure and maintains structural integrity when wet. A central core tube is made of perforated steel to prevent crushing.
The housing features a built-in primer pump (optional option for some variants – standard FG9604550030 does not include a primer pump but is compatible with an in-line priming bulb). The filter head also includes a fuel heater port (blanked) for cold climate retrofit. All sealing surfaces are diamond-turned to ensure leak-free performance under vibration.
The aluminum housing is hard-anodized (Type III) for wear resistance and then coated with a black epoxy topcoat, rated for 500 hours salt spray. The sediment bowl is made from impact-modified polycarbonate that resists cracking from diesel and sunlight, with a UV stabilizer additive. The bowl’s O-ring is a 70-durometer NBR that remains elastic down to -40°C.
The media pleats are bonded with a hot-melt adhesive that withstands fuel temperatures up to 100°C. A cellulose pre-filter captures larger rust and dirt particles, extending the life of the main synthetic media.
The FG9604550030 bolts directly to the original filter head (M16 x 1.5 ports with O-rings). The spin-on design requires no special tools: hand-tighten ¾ turn after gasket contact. The sediment bowl drain valve is accessible from below, allowing water draining without removing the filter.
For vehicles equipped with a water-in-fuel warning system, simply unscrew the port plug, install an M14 x 1.5 sensor (e.g., SINOTRUK Homan part WIF-S01), and connect to the vehicle harness. The filter orientation can be rotated 360° before final tightening.
1) Relieve fuel system pressure and place a container under the filter. 2) Unscrew the old filter using a strap wrench. 3) Clean the mounting head surface and apply a thin film of clean diesel to the new filter’s rubber gasket.
4) Screw on the new FG9604550030 until the gasket contacts, then tighten a further ¾ turn (do not overtighten). 5) If equipped, connect the WIF sensor to the pre-inserted boss. 6) Prime the fuel system by filling the filter with fuel (if no primer pump) or using the vehicle’s hand primer.
7) Start the engine and check for leaks. 8) Drain any water from the sediment bowl after the first 500 km, then routinely every 5,000 km or when the fuel quality is suspect. 9) Reset the filter life monitor (if fitted).
Inspect the water bowl weekly for sediment and water. If water is visible (interface line), open the drain valve and collect until clean fuel appears. Never allow the water level to reach the filter media. A water-in-fuel warning light (if sensor installed) indicates that draining is required.
Replace the filter element every 30,000 km or earlier if you notice a drop in engine power (possible restricted filter). Always use a genuine SINOTRUK Homan replacement element – counterfeit filters may lack the water separator screen and have lower burst strength. After replacing, reset the ECU adaptation if the vehicle has a fuel pressure sensor.
If you experience hard starting after filter replacement, ensure the system is primed correctly. Loosen the fuel outlet fitting and crank the engine until fuel flows without bubbles.
The FG9604550030 is manufactured according to ISO 9001:2015 and IATF 16949 standards. Each filter cartridge is 100% leak-tested (air pressure under water) and bubble-point tested to verify the retention rating. Random samples undergo ISO 19438 multi-pass testing to confirm 5µm (β5 ≥ 200) efficiency.
Additional validation includes a 1000-hour vibration test (20g, 10-2000 Hz) mounted on an engine, a thermal cycle test from -40°C to +100°C for 500 cycles, and a corrosion test (480h salt spray). The filter also meets OEM requirements for burst pressure (minimum 25 bar) and impulse fatigue (500,000 cycles at 12 bar).
A batch code is printed on the filter can. Counterfeit filters often have print that rubs off, use inferior media with lower efficiency, and lack the hydrophobic screen. Always verify the hologram on the box.
A fleet of 600 SINOTRUK HOWO trucks operating in West Africa (high water content in fuel) installed the FG9604550030 filter units. Over 18 months, injector replacement rates dropped by 80%, and the water drain bowl collected an average of 50-100 ml of water per truck per 10,000 km, preventing corrosion of common rails.
Another user – a European carrier using T7H trucks with Euro V engines – reported that fuel filter service intervals could be safely extended from 25,000 to 40,000 km due to the high dirt-holding capacity, with no visible fuel starvation.
Each genuine FG9604550030 fuel filter is packed in a sealed plastic bag inside a SINOTRUK Homan branded carton. The box includes a new O-ring for the head, water drain cap, and a QR code for authenticity verification.
The filter can has a laser-etched OEM number and production date code. The water bowl is clear and marked with “SINOTRUK Homan” and the part number. Counterfeit units may have a yellow-tinted bowl (genuine is water-clear), poor printing, or a missing hydrophobic membrane.
Always scan the QR code before installation. Using a fake fuel filter can lead to injector seizure, costing thousands in repairs.
