Installation & Maintenance Notes
For 2007.5-2009 Dodge Ram 6.7L Cummins trucks using the FS43257 fuel filter housing, general service steps include:
- Relieve fuel system pressure before servicing the filter housing.
- Drain any accumulated water from the housing’s water separator bowl.
- For routine service, replace only the internal filter cartridge (FS43258) and canister O-ring — the outer housing, WIF sensor and drain valve are reusable.
- Thoroughly lubricate the new O-ring before installation to ensure a proper seal, following the instructions included with each filter kit.
- Prime the fuel system per OEM procedure before restarting the engine.
- Follow your specific truck’s recommended service interval — always confirm against your Dodge Ram/Cummins maintenance schedule and duty cycle.
FAQ
Q: Does the FS43257 fit all 2007-2009 Dodge Ram 6.7L Cummins trucks? A: It fits 2007.5-2009 model year trucks with the 6.7L Cummins engine. It does not fit early-2007 trucks with the 5.9L Cummins engine (which uses a different filter housing), and it does not fit 2010+ trucks, which use a redesigned housing. Confirm your truck’s exact build date and engine before ordering.
Q: Do I need to replace the entire FS43257 housing every service interval? A: No — the FS2 Filter-in-Filter design allows you to reuse the composite canister, WIF sensor and drain valve. Only the internal filter cartridge (FS43258) and canister O-ring need to be replaced at each scheduled service.
Q: What’s the difference between IXIN’s FS43257 and the OEM Fleetguard filter? A: IXIN manufactures this housing assembly to match OEM dimensions and the documented filtration performance (98.7% efficiency at 5 microns). The main difference is price and lead time — IXIN offers factory-direct pricing for bulk and OEM orders without compromising fit or performance.
Q: Can I order the FS43257 with custom packaging or private label? A: Yes. IXIN supports customized packaging, labeling and media specifications for distributors and private-label buyers. Contact our sales team with your requirements.
