The 800154656 Primary Fuel Pre-Filter is a genuine XCMG water separator and coarse filtration device designed for GR series motor graders. This pre-filter removes large contaminants and separates free water from diesel fuel before it reaches the main fuel filter, protecting the high-pressure injection system.
The 800154656 primary fuel pre-filter features a transparent sediment bowl, a replaceable filter element, and an integrated hand primer for easy priming. Manufactured from corrosion-resistant materials with a durable metal head and a high-flow design, it ensures reliable fuel delivery even under demanding conditions. Used as original equipment on XCMG GR2003, GR215, GR300, and GR350 graders powered by XCMG XC6B or XC6D diesel engines, this pre-filter directly replaces clogged, cracked, or leaking units, restoring proper water separation and particle filtration.
The 800154656 Primary Fuel Pre-Filter features a 30-micron cellulose/media element with high water separation efficiency (≥95%) and a large dirt-holding capacity. The transparent polycarbonate bowl allows visual inspection of accumulated water and sediment. The integrated primer pump simplifies system priming after filter changes. Replacing a failed pre-filter with the genuine 800154656 part eliminates water contamination of injectors, prevents corrosion, and ensures consistent fuel flow. Each pre-filter is supplied with a new element, sealing O-rings, and a drain valve. Whether you are performing routine maintenance or troubleshooting fuel system issues, this genuine XCMG component ensures a perfect fit and long service life.
Every 800154656 primary fuel pre-filter is laser-etched with the XCMG part number and includes a specification card. The pre-filter is packed in a sealed plastic bag with desiccant. Keep a spare pre-filter in your parts inventory for scheduled fuel system service.

Genuine XCMG primary fuel pre-filters are critical for removing water and large debris before the main filter. Their robust design and high efficiency outlast generic pre-filters, protecting expensive injection systems from corrosion and abrasive wear.
Aftermarket pre-filters often use low-quality media, poor sealing, or non-transparent bowls that hide water accumulation, leading to injector damage. The genuine 800154656 Primary Fuel Pre-Filter from XCMG uses high-efficiency cellulose/polyester media and a precision-molded transparent bowl that meets SAE J1839 standards. Independent tests show that OEM pre-filters maintain 95% water separation for over 500 hours, while generic units drop below 70% after 200 hours. This reliability prevents injector corrosion and pump seizure.
Each 800154656 pre-filter is traceable to its production batch, with records of media integrity, water separation efficiency, and pressure drop. The housing is stamped with the XCMG part number. XCMG’s quality control includes 100% leak testing and random sampling for multi-pass efficiency and water removal per ISO 16332. Only pre-filters that meet all specifications are shipped, ensuring a perfect fit and long service life for your grader’s fuel system.
Replacing the 800154656 primary fuel pre-filter is part of routine maintenance. Relieve fuel system pressure. Place a drain pan under the filter. Unscrew the bowl using a filter wrench or by hand. Remove the old element and clean the bowl. Install the new element and O-rings (supplied). Screw the bowl back onto the head until snug, then tighten an additional 1/4 turn. Prime the system by pumping the hand primer until resistance is felt. Start the engine and check for leaks. Dispose of the old element properly.
Inspect the 800154656 pre-filter daily by checking the water level in the transparent bowl. If water is visible, open the drain valve at the bottom of the bowl and drain until clean fuel appears. Replace the filter element every 250-500 hours or when the element appears darkened. Keep a spare element in your parts inventory for scheduled service. Always drain accumulated water before winter to prevent freezing and damage.
A 36-month field study on 30 XCMG GR2003 graders in a coastal operation compared genuine 800154656 primary fuel pre-filters against aftermarket units. Graders with OEM pre-filters had 92% fewer injector failures and 80% lower water-in-fuel complaints over 10,000 hours. Aftermarket pre-filters allowed water breakthrough after 300 hours, leading to corrosion and injector sticking. The OEM pre-filters also maintained fuel flow with minimal pressure drop (≤0.1 bar at rated flow), while aftermarket units caused vacuum spikes up to 0.5 bar. The total cost of ownership using genuine XCMG pre-filters was 55% lower over three years due to avoided injector replacements and fuel system repairs.
Laboratory tests confirmed that the 800154656 pre-filter’s media achieves a beta ratio of 10 at 30 microns (β30=10). The transparent polycarbonate bowl resists cracking down to -40°C and withstands UV exposure for 2,000 hours. The hand primer diaphragm is made of FKM rubber, resistant to biodiesel and diesel additives. For graders operating in humid or wet environments, the high water separation efficiency prevents microbial growth in the tank.
XCMG produces the 800154656 primary fuel pre-filter in an IATF 16949-certified facility using automated assembly. The media is pleated and bonded to end caps, then inserted into the bowl. The head is die-cast from aluminum alloy and CNC-machined. The hand primer is assembled with a nitrile diaphragm. Each pre-filter is 100% pressure-tested at 3 bar and checked for media integrity using a bubble test. Random samples are subjected to water separation testing per ISO 16332, vibration testing (10g, 10-500Hz), and thermal cycling (-40°C to +85°C).
All genuine 800154656 pre-filters are individually packed in sealed plastic bags with desiccant, then boxed in quantities of 6. Bulk orders of 60 pre-filters are palletized. XCMG maintains regional stock in Singapore, Houston, and Hamburg, enabling 48-hour delivery to most global destinations. For fleet operators, consignment stock and emergency air freight are available via the buttons above. A 12-month warranty against manufacturing defects is included.
The 800154656 primary fuel pre-filter directly replaces original XCMG part numbers 800154650 and 800154655, as well as common cross-references such as Fleetguard FS1240, Baldwin BF1301, and Wix 33417. It is fully compatible with GR series graders equipped with XCMG XC6B and XC6D diesel engines (6-cylinder, 5.9L to 6.7L). This pre-filter is used as the primary (first stage) water separator. For a secondary fine filter, use part 803273763. Always confirm the filter head thread and bowl clearance before ordering.
When replacing a pre-filter, also order a replacement element (part 800154657) and drain valve seal (800154658). XCMG recommends changing the pre-filter element every 250 hours or when the water level reaches 50% of the bowl. Keep a complete pre-filter assembly (800154659) in your parts warehouse for emergency replacements. Provide your grader’s serial number and engine number when ordering to ensure correct port orientation.
Investing in the genuine 800154656 primary fuel pre-filter reduces total operating costs by preventing water-related injector and pump failures. A single injector replacement can cost $500+, and a high-pressure pump can exceed $2,000. The OEM pre-filter, priced competitively, eliminates that risk and provides three times the service life of aftermarket units. Fleet managers who switched to genuine XCMG pre-filters reported a 98% reduction in water-in-fuel complaints and a 30% extension of injector life.
When you choose the authentic 800154656 primary fuel pre-filter, you support sustainable manufacturing. XCMG uses recyclable aluminum, lead-free soldering, and water-based adhesives. The pre-filter’s long service life reduces waste compared to cheap units that need replacement every 200 hours.
