Superior water separation and large particle filtration for diesel engines – The OEM 612600081327 Fuel Coarse Filter Element is designed as the first line of defense against contaminants, removing bulk water, rust, and dirt particles as small as 30 microns.
This heavy-duty filter element safeguards fuel injection pumps and injectors from abrasive damage, extending engine life. For guaranteed compatibility and reliable performance, always choose genuine Sinotruk Homan parts.
The 612600081327 meets original equipment standards for HOWO, SHACMAN, and other heavy-duty trucks. Its high-efficiency coalescing media removes up to 95% of free water, preventing corrosion and microbial growth in fuel systems.
The 612600081327 Fuel Coarse Filter Element uses a high-capacity pleated cellulose/synthetic blend media, specifically engineered for first-stage filtration. It captures rust, sand, and other large debris before fine filtration.
The integrated water coalescing layer forces microscopic water droplets to merge and fall into a collection bowl. This dual-action design ensures that only clean, dry fuel reaches the precision injection system.
Fleets using the 612600081327 report 40% fewer injector failures and significantly reduced downtime. The filter element also meets ISO 4020 requirements for diesel fuel filtration.
Advanced coalescing media removes free water down to 15 ppm, protecting injectors from corrosion and diesel microbial contamination.
With >80 grams of dust holding capacity (ISO 4020), the 612600081327 provides long service intervals even in dusty environments.
Special resin treatment prevents wax clogging at -20°C, ensuring reliable winter operation for fleets in arctic regions.

The 612600081327 Fuel Coarse Filter Element features a three-stage purification process: first, a high-loft outer layer traps large particles; second, a dense inner layer captures medium debris; third, a water-repellent screen forces coalesced water to drop out.
The media is resin-impregnated to maintain structural integrity even when saturated with water or biodiesel blends (B20 compatible). The center tube is made of perforated steel with a burst strength of 10 bar, preventing collapse under heavy fuel flow.
Each element is 100% end-capped with epoxy-sealed steel to prevent bypass. The integrated gasket uses a unique groove design that eliminates leaks common with flat gaskets.
Unlike standard sedimenters, the 612600081327 employs a multi-layer coalescing matrix. Micro-glass fibers create a tortuous path that captures emulsified water droplets as small as 5 microns.
These droplets then combine into larger drops that gravity-separates into the water bowl. This technology is critical for ultra-low sulfur diesel, which tends to hold more suspended water.
The element also includes a hydrophobic screen that repels water, ensuring only fuel passes through to the fine filter stage.
The 612600081327 directly replaces OEM filter elements on SINOTRUK HOWO A7, T7H, SHACMAN F3000, and many Weichai, Cummins, and MAN engines with the same thread and dimensions.
Always lubricate the new gasket with clean diesel fuel before installation. Tighten by hand until gasket contact, then further 1/2 to 3/4 turn (max 30 Nm). Do not overtighten as it may distort the gasket.
After replacement, prime the fuel system by pumping the hand primer until resistance is felt, then start engine and check for leaks.
Follow these steps for correct replacement of the 612600081327 Fuel Coarse Filter Element: 1) Relieve fuel system pressure and place a container under the filter head.
2) Unscrew the old element using a filter wrench. Clean the mounting surface and inspect the water-in-fuel sensor (if equipped).
3) Apply a thin coat of clean diesel fuel to the new element’s gasket. Screw on until the gasket contacts the base, then tighten an additional 2/3 turn.
4) Prime the system using the hand primer (usually 30-50 strokes) until firm resistance is felt. 5) Start the engine and check for leaks. 6) Verify water bowl drain valve is closed.
Always replace the element at every scheduled fuel filter service, typically every 30,000 km or 500 engine hours.
The 612600081327 should be replaced when the water-in-fuel warning light illuminates or at every oil change interval for severe duty. The element is not cleanable or reusable.
For high-humidity or wet fuel environments, inspect the water bowl every week and drain accumulated water. Use a fuel additive biocide if microbial growth is suspected.
If the engine experiences power loss or hard starting, replace the coarse filter element first, as it is the most common restriction point.
Each 612600081327 Fuel Coarse Filter Element is produced in an IATF 16949 and ISO 9001 certified facility. Rigorous quality checks include: (1) Bubble point integrity test, (2) Multi-pass filtration efficiency test per ISO 4020.
(3) Water separation efficiency test per SAE J1839, (4) Burst pressure test (minimum 8 bar differential), (5) Flow restriction test at rated flow, and (6) Compatibility testing with B20 biodiesel.
The element also passes a 200-hour pulsed flow fatigue test and a thermal cycling test from -30°C to +80°C. Each batch comes with a certificate of conformance.
An Australian mining company operating 120 CAT and HOWO haul trucks switched to the 612600081327 Fuel Coarse Filter Element. After 12 months, they saw a 52% reduction in high-pressure pump failures and eliminated water-related injector seizures.
A Brazilian sugar cane transport fleet reported that using the 612600081327 extended their fuel filter change intervals from 200 to 350 hours, saving over 15,000 USD annually in maintenance costs.
Each genuine 612600081327 Fuel Coarse Filter Element is packaged in a sealed, moisture-resistant cardboard box with a tamper-evident label. The element end cap features a laser-etched batch code and SINOTRUK Homan logo.
A unique QR code on the box links directly to the authenticity verification page. Counterfeit elements often use non-impregnated paper that swells with water, causing fuel starvation. Always inspect the media color: genuine is dark brown with uniform pleats.
Purchase only from authorized distributors to guarantee genuine media technology and water separation performance.
Summary: The SINOTRUK Homan Fuel Coarse Filter Element (OEM 612600081327) delivers superior water separation and high dirt capacity for diesel engines. Protect your injection system with genuine OEM filtration — the proven choice for maximum uptime.
