'07.5-'09 Cummins 6.7L Fleetguard FS43257 Fuel Filter & Shell Assembly
2007.5-2010 6.7L Fleetguard FS2
Cummins Filtration has released a new high performance Fleetguard® FS2: Filter-in-Filter technology for the Dodge Ram trucks withthe 6.7L Cummins turbo diesel engines. The new FS43257 filter assembly is an upgrade for the ’07 – ’09 Dodge Ram which provides the filtration performance of two filters in a single, reusable filter canister.
The FS2: Filter-in-Filter Fuel System Protection product provides optimally designed filter media in a unique construction to achieve:
• Unmatched free and emulsified fuel/water separation – Ensuring greater protection from water-related corrosion for modern high pressure fuel systems.
• 2-stage particle removal - 5* micron filtration rating - for exceptional fuel system protection without the hassle of extra filters and fuel plumbing arrangements.
• Customer-requested optimal fuel system protection in a design that allows reuse of the filter canister and replacement of only the filter cartridge at service time.
Cummins and Chrysler began applying this high-performance filter to all new engines and trucks effective January 2009. All owners of 2007 – 2009 Dodge Ram trucks with a 6.7L Cummins turbo diesel engine can use the new filter without the need for additional plumbing or hardware.
The FS43257 Filter-in-Filter is a direct fit replacement for the original FS43252 single-stage filter.
To minimize the waste stream associated with fuel filter changes, only the internal filter cartridge and canister O-ring (kit part# FS43258) must be changed during service - the tough composite filter canister plus the water-in-fuel (WIF) sensor and the filter drain valve can be reused over and over.**
Application and Part Number Cross Reference: 2007 – 2009 Dodge Ram® 2500, 3500, 4500 and 5500 vehicles with the 6.7L Cummins® turbo diesel engine.
