Cummins Fleetguard fuel filter FF5580=3973232 is a core fuel system purification component, intercepting diesel impurities and water to protect injectors and high-pressure pumps, compatible with Cummins ISF, QSF series engines. It features multi-layer composite filter media (including glass fiber and hydrophobic layer) for 99.8% filtration of particles above 5μm and free water, preventing contamination-induced wear and blockages while improving fuel atomization efficiency, reducing fuel consumption by 3%-5%.
The filter adopts high-strength galvanized steel housing and nitrile rubber seals, withstanding -40℃ to 80℃ temperatures and 16bar pressure, compatible with Cummins ISF2.8, ISF3.8, QSF3.8 models. Its built-in bypass valve ensures continuous fuel supply during clogging, with dirt-holding capacity ≥15g; replacement cycle is 2000-2500 hours under normal conditions, extending fuel system component life.
Ningbo Qiuning offers original and aftermarket options: Original meets Fleetguard ISO 4020 standards, with filter media/structure matching OE systems, each tested for flow resistance, ideal for heavy-duty operations requiring high filtration stability; Aftermarket passes third-party water separation/filtration tests, with ≥95% OE performance, priced at 50%-60% of original, suitable for regular maintenance and budget constraints.
Ensure seals are intact during installation, tighten end caps to specified torque to avoid leakage. We have sufficient stock and support global shipping within 48 hours. Our technical team can provide guidance on matching model inquiries and replacements. Welcome to inquire and purchase:
