Product Features

• Structure: A spin-on design combining a high-efficiency filter media core with an integrated transparent water collection bowl and drain valve. The housing is made of corrosion-resistant steel, and the bowl allows for visual inspection of accumulated water.

• Performance: The multi-layer filter media captures 98% of particles larger than 5 microns, while the water separation function removes free water from fuel to prevent corrosion and injector damage. The drain valve enables easy water removal without filter disassembly.

• Design: Direct-fit replacement with standard thread size, ensuring compatibility with original filter housings and tool-free installation.

Core Function

• Removes large contaminants and water from diesel fuel before it reaches the main fuel filter and high-pressure injection system, extending the service life of downstream components.

• The transparent water bowl provides visual monitoring of water accumulation, allowing timely drainage to prevent fuel system damage.

• Maintains consistent fuel flow and pressure, ensuring reliable engine performance and reducing fuel consumption.

Fuel Prefilter Element VG1540080311 SINOTRUK – OEM-Grade Diesel Filtration for HOWO & Steyr Heavy Trucks

Every drop of diesel your engine drinks passes through this guardian first. The Fuel Prefilter Element VG1540080311 is purpose-built for SINOTRUK WD615 series engines, standing between contaminated fuel and your injection system. It captures particulate matter down to 10 microns and separates emulsified water before they ever reach your high-pressure fuel pump — protecting components worth thousands of dollars with a filter that costs a fraction of a single repair.

Sourced directly from our factory-partner network in China, this genuine-spec element delivers the exact dimensional fit, media density, and flow capacity that SINOTRUK engineers specified. Whether you manage a mixed fleet of HOWO A7 tractor heads, Steyr King dump trucks, or SITRAK C7H logistics vehicles, this prefilter element keeps your fuel system breathing clean.

Key Functions & Buyer Benefits

Superior Contaminant Removal

The multi-layer cellulose-synthetic composite media traps rust particles, sand, and pipe scale ≥10 µm at a filtration efficiency exceeding 95%. Your injectors and plunger pairs stay protected, extending overhaul intervals by up to 30%.

Effective Water Separation

An integrated hydrophobic barrier coalesces free and emulsified water, channeling it to the sediment bowl for manual drainage. This prevents microbial growth and corrosion inside fuel rails — a common failure mode in tropical and humid operating environments.

Exact OEM Dimensional Fit

Manufactured to the original VG1540080311 blueprint: correct outer diameter, seal groove depth, and center-bolt bore. No adapter kits, no gasket trimming — it drops in and seals the first time.

Optimized Flow Rate

Rated for a clean-element pressure drop of ≤8 kPa at 300 L/h, ensuring your WD615 engine receives unrestricted fuel supply even under full-load hill-climbing conditions.

Cost-Effective Fleet Maintenance

Factory-direct pricing from JINAN METTLEAD AUTO SALES CO.LTD. eliminates middleman markups. Bulk procurement programs are available for fleet operators replacing 50+ units per cycle.

Technical Specifications

Application Scenarios

The Fuel Prefilter Element VG1540080311 serves as the first line of defense in the fuel delivery system of SINOTRUK WD615 series diesel engines. It filters out solid impurities — including rust flakes, silica dust, and wax crystals — while simultaneously separating water from diesel fuel before it reaches the fine filter and injection pump.

This element is a direct fit for the following heavy-duty truck platforms:

• SINOTRUK HOWO A7 6×4 Tractor Head — long-haul logistics and container transport
• SINOTRUK HOWO 8×4 Dump Truck — mining and construction site haulage
• SINOTRUK Steyr King Tipper — earthmoving and aggregate delivery
• SINOTRUK SITRAK C7H 4×2 Cargo Truck — express freight corridors
• SINOTRUK HOWO Concrete Mixer Truck — urban and suburban concrete delivery

If your fleet operates in dusty environments, uses fuel from roadside stations, or runs in regions with high-humidity climates, this prefilter element works overtime to keep your injectors and fuel pump alive.

Frequently Asked Questions — Fuel Prefilter Element VG1540080311

Q1: What is the difference between a fuel prefilter element and a fuel fine filter element?

The Fuel Prefilter Element VG1540080311 is the primary (coarse) stage filter. It removes larger particles (≥10 µm) and separates water before fuel enters the fine filter. The fine filter (typically VG1540080110) then captures smaller particles (≥3–5 µm). Both must be replaced together for complete system protection.

Q2: How often should I replace the VG1540080311 fuel prefilter element?

SINOTRUK recommends replacement every 10,000–15,000 km under normal operating conditions. If your trucks operate in extremely dusty environments or use lower-quality diesel, shorten the interval to 8,000 km. Always drain the water separator bowl during routine inspections.

Q3: Will this fuel prefilter element fit non-SINOTRUK engines?

VG1540080311 is dimensionally designed for SINOTRUK WD615/WD618 engine fuel prefilter housings. Some Weichai WP10 applications share the same housing design. We recommend confirming your housing model before ordering. Our team can cross-reference your current part number free of charge.

Q4: How can I verify that this is a genuine-specification element and not a low-quality copy?

Every element we supply passes in-house quality inspection including dimensional measurement, media burst-pressure testing, and flow-rate validation. We can provide test reports and photos upon request. Factory visits to our Jinan facility are also welcomed for key accounts.

Q5: What happens if I delay replacing a clogged fuel prefilter element?

A saturated prefilter element restricts fuel flow, causing power loss, rough idling, and hard starts. Worse, unfiltered water and debris bypass the element and attack your injection pump plungers and nozzle needles — leading to repair costs 50–100× the price of a new filter element.
