Cummins engine spare parts Fuel filter C4365703 in stocked

Equipped with a multi-layer synthetic media (80% polyester, 20% glass fiber) and a 5-micron absolute filtration rating, the filter captures 99.9% of contaminants in diesel fuel—including dirt, rust, and carbon particles that cause premature wear to fuel injectors and pumps. The media features a pleated design (120 pleats, 0.2mm pleat height) that increases surface area by 300% compared to flat media, enabling a dirt-holding capacity of 120g (exceeding Cummins’ requirement of 100g). It also includes a water-separating layer (hydrophobic coating) that removes up to 95% of free water from fuel—critical for preventing fuel system corrosion and microbial growth (common in high-humidity regions). This high-precision filtration extends injector service life by 50% and reduces fuel pump maintenance costs by 35%

Engineered to withstand the harsh conditions of fuel systems—pressure fluctuations (up to 10 bar), temperature extremes (-40°C to 120°C), and chemical exposure (diesel, biodiesel blends)—the filter features a durable, corrosion-resistant design:

Housing: High-density polyethylene (HDPE) housing with a tensile strength of 30 MPa, resisting impact damage (tested to 10J impact with no cracking) and fuel permeation (no fuel loss after 1,000 hours of exposure).

Seals: Nitrile rubber O-rings (70 Shore A hardness) that maintain a tight seal under temperature changes, preventing fuel leaks even in extreme cold (no hardening at -40°C).

End Caps: Epoxy-bonded polyester end caps that secure the media in place, resisting delamination under high fuel flow (up to 15 L/min).

These components ensure the filter remains intact and functional for 15,000 km (Cummins’ recommended service interval), even in dusty or off-road environments

The filter is designed to maintain stable fuel pressure and flow—critical for consistent engine performance:

Pressure Drop Control: The media’s low-resistance design ensures a maximum pressure drop of 0.5 bar at full flow (15 L/min), preventing fuel starvation during high-load operation (e.g., heavy acceleration, hauling).

Anti-Cavitation Design: A built-in bypass valve (activating at 1.2 bar pressure drop) ensures fuel flow continues even if the media is fully clogged—preventing engine shutdown in remote areas.

Uniform Flow Distribution: The filter’s inlet baffle distributes fuel evenly across the media surface, avoiding localized clogging and extending the filter’s effective service life.

By maintaining stable pressure and flow, the filter ensures the engine operates at peak efficiency (fuel consumption reduced by 2–3%) and avoids power loss during critical operations

Designed for efficient replacement by fleet technicians, the filter simplifies maintenance with user-friendly features:

Tool-Free Installation: The bayonet-style mounting allows installation/removal with a simple 90° twist—no wrenches or specialized tools needed, reducing replacement time to 5 minutes.

Visual Indicators: A transparent water-level window on the housing lets technicians check water accumulation without disassembling the filter, and a pressure differential indicator (optional) signals when the filter needs replacement.

Disposal-Friendly Design: The HDPE housing is recyclable, and the media is non-toxic—complying with global environmental regulations (e.g., EU RoHS, EPA guidelines).

Each unit undergoes 100% testing, including filtration efficiency (ISO 4020), pressure drop (ISO 16889), and leak verification (10 bar pressure test), backed by a 12-month OEM warranty against defects (e.g., media failure, housing cracking, seal leaks)
