Fleetguard FF422088PMX Filter Element

Fleetguard FF422088PMX is a high-performance spin-on fuel fine filter element, engineered for the high-pressure common rail systems of Cummins ISG11.8/12.9 heavy-duty diesel engines, which are widely fitted in Foton Auman EST/GTL long-haul tractors and Daimler commercial vehicles. It adopts Fleetguard’s proprietary NanoNet® high-density filter media, delivering 99.8% filtration efficiency at 4 microns—surpassing standard 5-micron filters.
This enables it to capture submicron soot particles and water droplets in low-quality diesel, effectively preventing abrasion and clogging of precision components like electronically controlled injectors and high-pressure fuel pumps, ensuring consistent engine power output even under continuous high-load operations.Key specifications: 102mm outer diameter, 195mm height, 1-1/2″-12UNF-2B thread, with a 95mm outer seal diameter, perfectly matching the original filter housing
It is integrated with a water-in-fuel (WIF) sensor port and a pressure relief valve, supports tool-assisted quick replacement, and maintains stable performance in the -40°C to 130°C extreme temperature range. As an OEM-grade replacement for Cummins 3694659, it is a critical maintenance part for long-haul logistics fleets.

Advantages of FF422088PMX Filter Element

Submicron Precision Filtration: 4-micron filtration efficiency of 99.8% captures ultra-fine contaminants that standard filters miss, reducing injector failure rates by 35% and extending fuel system service life by 30%.
ISG Engine Customization: Tailored for Cummins ISG11.8/12.9 engines, optimizing fuel flow rate to match the engine’s high-torque characteristics, avoiding pressure loss and power attenuation issues.
Enhanced Water Separation: Hydrophobic media surface repels 99% of free water in diesel, preventing fuel system corrosion and cavitation damage in humid or rainy operating environments.
Heavy-Duty Structural Design: Reinforced steel casing with anti-corrosion coating withstands 8bar fuel pressure and 3G vibration loads, adapting to bumpy road conditions of long-haul transportation.
Fleet Cost Optimization: OEM-equivalent quality with 22% lower procurement costs than original parts, and 15% longer service intervals than conventional filters, cutting total fleet maintenance expenses.
