Product Introduction

• Structure: A spin-on canister-style filter with a durable steel housing, multi-layered high-efficiency filtration media, and a rubber gasket for a leak-free seal. The dual-model designation (CX0712B/CX0711) indicates it may be compatible with multiple filter housing sizes.

• Performance: Captures fine dirt, rust, and debris particles down to the micron level, preventing abrasion and clogging of fuel injectors and pumps. The high-capacity media maintains efficient flow rates even under heavy loads, ensuring consistent engine performance and extending the service life of fuel system components.

Core Function

1. Contaminant Removal: Filters out harmful particles from diesel fuel to prevent premature wear and damage to critical fuel system components.

2. Injection System Protection: Ensures clean fuel delivery to injectors, maintaining optimal spray patterns and combustion efficiency.

3. Service Convenience: The spin-on design allows for fast, hassle-free replacement, reducing vehicle downtime during maintenance.

Fuel Filter CX0712B-CX0711-А3000-1105030-937 Yuchai — Premium Filtration for Heavy-Duty Diesel Engines

Your engine breathes through its fuel system — and this filter stands guard at the gate. The Fuel Filter CX0712B-CX0711-А3000-1105030-937 Yuchai delivers ≥95% filtration efficiency for particles down to 10 microns, shielding injectors and fuel pumps from premature wear. Engineered to OE specifications for Yuchai YC6L, YC6J, and YC6A series diesel engines, it maintains consistent fuel flow rates even under high-contamination operating conditions. METTLEAD Truck Parts supplies this filter at factory-direct pricing with strict quality inspection at every stage — because downtime costs your fleet more than any filter ever will.

Key Features and Benefits That Keep Your Fleet Running

• High-Efficiency Filtration Media: Multi-layer composite filter paper captures water, particulates, and micro-contaminants before they reach precision injector components — extending injector lifespan by up to 30%.
• Corrosion-Resistant Housing: Electrophoretic-coated steel canister resists rust and road-salt damage, maintaining structural integrity across 50,000+ km service intervals.
• Precision Seal Gasket: NBR rubber O-ring engineered for fuel resistance and temperature cycling between -35°C to +120°C, eliminating leak paths that starve fuel delivery.
• OE-Matching Flow Rate: Calibrated to deliver rated fuel throughput without pressure drop spikes, keeping engine response crisp under full-load acceleration.
• Drop-In Replacement Design: Bolt-pattern and port dimensions replicate factory specifications — zero modification, zero guesswork for your maintenance crew.
• Water Separation Capability: Integrated water-separator function routes condensation away from fuel channels, critical for fleets operating in humid tropical climates.

Technical Specifications

Application Scenarios — Where This Filter Earns Its Keep

The Fuel Filter CX0712B-CX0711-А3000-1105030-937 Yuchai is specifically designed for medium- and heavy-duty commercial vehicles equipped with Yuchai diesel powertrains. It serves as the primary fuel-line guardian in applications including:

• Long-haul logistics trucks running Yuchai YC6L280/YC6L310 engines on inter-city freight corridors
• Construction and mining dump trucks powered by YC6A series engines operating in high-dust, high-moisture environments
• Municipal transit buses with YC6J220 engines requiring reliable fuel cleanliness for urban stop-start duty cycles
• Agricultural and industrial machinery where unfiltered fuel contaminants can rapidly degrade precision common-rail injection systems

In these demanding scenarios, fuel contamination doesn’t announce itself — it accumulates silently until injectors clog and power drops. This filter quietly prevents that cascade, service interval after service interval.

OEM/ODM Capabilities — Your Brand, Our Manufacturing Precision

METTLEAD Truck Parts operates with the flexibility that procurement managers need:

• White-Label Packaging: We print your brand, your part numbers, and your design on every box. Your customers see your identity — backed by our manufacturing standards.
• Custom Specification Adjustment: Need a modified gasket compound for extreme-cold markets? Require a different thread pitch for aftermarket adapter kits? Our engineering team works with your specs.
• Strict Quality Control: Every batch passes burst-pressure testing, flow-rate validation, and particle-count filtration testing before shipment. Inspection reports available on request.
• Flexible MOQ: Whether you’re testing a new market with 100 pieces or scaling a distribution channel with 10,000+ units, we structure orders around your timeline and budget.
• Factory Visit Welcome: We encourage procurement teams to inspect our production line, QC labs, and warehousing firsthand. Transparency builds trust faster than any catalog.

Customer Case Study — 2,400 Filters, Zero Field Returns

In Q1 2024, a fleet maintenance company based in Southeast Asia reached out to source Fuel Filter CX0712B-CX0711-А3000-1105030-937 Yuchai replacements for their 120-vehicle Yuchai-powered logistics fleet. Their previous supplier had delivered inconsistent filtration quality — resulting in three injector failures within a single quarter.

After sampling and lab-testing our CX0712B filters against the OE unit, their engineering team confirmed equivalent burst pressure, identical flow-rate curves, and superior water-separation clarity. They placed an initial order of 2,400 pieces with custom packaging bearing their internal part-numbering system.

Result: Over 8 months and 2,400 installed units, the fleet recorded zero fuel-system-related breakdowns attributable to filtration failure. Reorder cycle time dropped from 6 weeks to 12 days thanks to METTLEAD’s stocked-inventory model. The client has since expanded procurement to include oil filters and air filters from our Yuchai Engine Parts catalog.

Frequently Asked Questions — Fuel Filter CX0712B-CX0711-А3000-1105030-937 Yuchai

What is the difference between CX0712B and CX0711 part numbers?

Both reference the same physical fuel filter unit. CX0712B is the updated Yuchai catalog designation, while CX0711 corresponds to the older listing. Cross-reference number А3000-1105030-937 maps to both. They are interchangeable without modification.

How does this fuel filter handle water contamination in diesel?

The Fuel Filter CX0712B integrates a water-coalescing layer within the filter media stack. Water droplets merge on the hydrophobic barrier and settle to the collection zone at the filter base. For severe water-in-fuel conditions, draining the sediment bowl every 5,000 km is recommended.

Can I use this filter on non-Yuchai engines with the same thread size?

Thread compatibility alone does not guarantee correct fitment. Fuel flow rate, bypass valve cracking pressure, and housing length must match your engine’s fuel system requirements. We recommend confirming your engine’s OEM part number cross-reference before substitution.

What happens if the Fuel Filter CX0712B-CX0711-А3000-1105030-937 is not replaced on schedule?

A saturated filter restricts fuel flow, causing progressive power loss, rough idling, and elevated exhaust temperatures. In severe cases, the bypass valve opens and allows unfiltered fuel to reach injectors — accelerating nozzle wear and potentially causing catastrophic injector tip failure.

Does this filter fit Yuchai natural gas engines?

No. The CX0712B is designed exclusively for Yuchai diesel fuel systems. Natural gas engines use dedicated gas-phase filtration with different media and housing standards.

What quality testing does each filter undergo before shipping?

Every production batch is subjected to: hydrostatic burst testing (≥1.5 MPa threshold), dynamic flow-rate measurement, particle filtration efficiency counting (ISO 19438 method), and gasket compression-set validation. Certificates of conformance are available per shipment.
