Product Features

• Structure: A spin-on canister filter with integrated oil-water separation functionality. It features a high-efficiency filter media and a drain valve at the bottom for water removal.

• Performance: Effectively filters out contaminants (down to 3–5 μm) from diesel fuel and separates water, protecting the fuel injection system from wear and corrosion. The spin-on design allows for quick and easy replacement.

• Design: Directly interchangeable with the original equipment filter, ensuring a perfect fit and sealing with the engine fuel system.

Core Function

1. Fuel Filtration: Removes dirt, rust, and other particulates from diesel fuel to prevent damage to injectors and the fuel pump.

2. Water Separation: Separates water from the fuel, which is critical for preventing corrosion and injector failure in the high-pressure fuel system.

3. Maintenance Indication: Equipped with a drain valve to periodically remove accumulated water, as instructed on the label.

Oil-Water Separator Filter Element D00-305-03+A SHANGCHAI – Premium Replacement for Heavy-Duty Diesel Engines

Water contamination silently destroys diesel fuel systems. A single droplet passing through your injectors can trigger corrosion, cavitation, and catastrophic pump failure — costing thousands in unplanned downtime. The Oil-Water Separator Filter Element D00-305-03+A, engineered specifically for SHANGCHAI diesel engines, stands as your frontline defense against moisture-related fuel system damage. Sourced directly from METTLEAD Truck Parts’ quality-controlled supply chain, this filter element delivers OE-equivalent separation efficiency at a factory-direct price point that strengthens your procurement margins.

Whether you manage a mixed fleet of construction vehicles or maintain a logistics operation running SHANGCHAI-powered trucks across demanding terrain, this filter element keeps your fuel clean, your injectors protected, and your engines running at peak thermal efficiency.

Key Functions and Buyer Benefits

Superior Water Separation Performance

This filter element employs a multi-layer coalescing media structure that captures free water and emulsified moisture from diesel fuel with a separation efficiency exceeding 95%. The hydrophobic barrier forces water droplets to coalesce and drain into the collection bowl, ensuring only clean, dry fuel reaches your injection system.

Extended Particulate Filtration

Beyond water removal, the D00-305-03+A traps solid contaminants — rust particles, dirt, and pipe scale — down to 10 microns. This dual-action filtration protects high-pressure common rail injectors and fuel pumps from abrasive wear, extending component service life by up to 30%.

Engineered for SHANGCHAI Engine Compatibility

Dimensionally matched to SHANGCHAI SC series engine fuel systems, this element drops directly into OEM filter housings without modification. The sealing gasket geometry and flow-path design replicate original specifications, eliminating bypass risk and ensuring rated fuel flow under all operating loads.

Cost-Effective Fleet Maintenance

METTLEAD’s factory-direct pricing model removes intermediary markups. For fleet procurement managers handling bulk replacement schedules, this translates to 15–30% cost savings per unit compared to aftermarket alternatives — without sacrificing filtration integrity.

Reliable Service Intervals

Built with high-capacity media that resists premature clogging, this filter element maintains consistent pressure differential across its rated service life. Operators can confidently follow standard 500-hour or 20,000 km replacement intervals depending on fuel quality conditions.

Technical Specifications

Application Scenarios and Compatible Vehicle Models

The Oil-Water Separator Filter Element D00-305-03+A SHANGCHAI serves a broad range of heavy-duty applications where SHANGCHAI SC series engines provide the power. Typical deployment scenarios include:

• Long-Haul Logistics Trucks — SHANGCHAI-powered tractor units operating on intercity freight corridors where fuel station quality varies significantly.
• Construction and Mining Equipment — Wheel loaders, excavators, and dump trucks fitted with SC7H/SC9D series engines working in high-dust, high-moisture environments.
• Municipal and Utility Vehicles — Refuse trucks, road sweepers, and water tankers using SHANGCHAI powertrains in urban service fleets.
• Agricultural Machinery — Harvesters and tractors equipped with SHANGCHAI engines operating in humid field conditions where condensation contamination is common.
• Power Generation Sets — Stationary and mobile gensets running SHANGCHAI diesel engines that require consistent fuel purity for stable output.

This filter element is cross-referenced to fit vehicles and equipment from manufacturers including SANY, XCMG, LIUGONG, SHANTUI, and ZOOMLION that integrate SHANGCHAI engine platforms.

Strict Quality Control Process

Every batch of D00-305-03+A filter elements undergoes a rigorous inspection protocol:

1. Incoming raw material verification (media porosity, gasket durometer testing)
2. In-process dimensional checks against OEM housing tolerances
3. Final burst pressure and flow resistance testing
4. Water separation efficiency validation on sample units per lot

Flexible Order Quantities

From trial orders of 50 pieces to container-load procurement of 10,000+ units, METTLEAD scales production to match your demand cycle. We understand that procurement managers need responsive supply partners — not rigid MOQ barriers.

Fast and Reliable Delivery

Frequently Asked Questions

What happens if I don’t replace the oil-water separator filter element on schedule?

A saturated D00-305-03+A element loses its ability to coalesce and drain water effectively. Moisture passes through to the fuel injection system, causing micro-pitting on injector needle valves and accelerating corrosion inside the high-pressure pump. Over time, this leads to rough idling, power loss, increased fuel consumption, and eventually component failure requiring expensive overhaul.

How do I confirm this filter element fits my specific SHANGCHAI engine model?

The D00-305-03+A is the OEM-designated part number for SHANGCHAI SC series fuel-water separator assemblies. Cross-reference this number against your engine’s parts manual or contact our technical team with your engine nameplate data (model, serial number, production year) for confirmation.

Can this filter element handle biodiesel or blended fuels?

The synthetic coalescing media is compatible with standard diesel and low-sulfur diesel fuels. For biodiesel blends above B20, the media may experience accelerated degradation due to the solvent properties of fatty acid methyl esters. We recommend shortened replacement intervals (300–400 hours) if operating on high-percentage biodiesel blends.

What is the difference between this element and a standard fuel filter?

A standard fuel filter primarily captures solid particulates. The D00-305-03+A oil-water separator filter element performs dual-function filtration — it removes both particulate contamination and free/emulsified water through its coalescing media layers. It sits upstream of the fine fuel filter in the system, acting as the first stage of fuel purification.

How should I store spare filter elements before installation?

Store in a cool, dry environment away from direct sunlight. Keep the element in its sealed packaging until installation to prevent dust contamination of the media surface. Shelf life under proper storage conditions is approximately 24 months from manufacture date.

Do you offer volume pricing for recurring fleet orders?

Yes. METTLEAD provides tiered pricing structures for procurement managers placing scheduled repeat orders. The more consistent your order volume, the more competitive your per-unit cost becomes. Reach out to discuss a tailored pricing agreement for your fleet size.
