FORD 6.7L POWERSTROKE 5-MICRON FUEL WATER SEPARATOR FD-4615

iFJF part No.: FJ-FD4615. Ford 6.7L Powerstroke 5-Micron Fuel Water Separator FD-4615 Superior CP4.2 Protection The FD-4615 5-Micron Fuel Water Separator provides twice the filtration of the factory 10-micron filter for 2011-2016 Ford 6.7L Powerstroke engines. If you're protecting your Bosch CP4.2 high-pressure fuel pump and you absolutely should be this 5-micron upgrade is the single most important maintenance decision you'll make.

The CP4.2 pump's internal clearances are measured in single-digit microns every 5-micron particle stopped is one that won't score your pump's precision-machined internals. Advanced Water Separation: Multi-layer media with hydrophobic barrier removes both free and emulsified water from diesel fuel the #1 cause of CP4.2 corrosion and seizure. High-Flow Design: Engineered for full fuel volume under all operating conditions, including WOT towing at maximum GVWR. No restriction, no performance loss. Extended Dirt-Holding Capacity: Greater media surface area means longer service life despite finer filtration. Same 15,000-22,500 mile interval as the factory filter. Direct Factory Replacement: Fits the factory plastic fuel filter housing no adapters, no modifications, no special tools. Technical Specifications Part Number FD-4615 OEM Cross-Reference BC3Z-9N184-B (factory replacement, upgraded filtration) Filtration Rating 5 Micron Absolute (factory: 10 micron) Filter Type Cartridge-style fuel water separator Service Interval Every 15,000-22,500 miles or 12 months Housing Fitment Factory plastic housing (frame-mounted). Also compatible with iFJF 121003 All-Metal Conversion Kit 5-Micron vs 10-Micron Why It Matters The factory 10-micron filter stops particles the size of a red blood cell. The FD-4615 stops particles half that size . The Bosch CP4.2 high-pressure fuel pump generates 29,000+ psi and relies on diesel fuel for both cooling and lubrication. Internal clearances between the pump's roller tappets, cam lobes, and housing are measured in microns. A single particle that passes through a 10-micron filter can initiate the scoring cascade that eventually destroys the pump sending metal debris through all 8 injectors, both fuel rails, and the entire high-pressure system. Complete repair: $8,000-$12,000. Installation Guide Locate Filter Housing: Frame-mounted on the driver side, under the vehicle near the fuel tank. Drain Water Separator: Open the drain valve and collect any water/fuel in a suitable container. Remove Housing Cap: Use the appropriate filter wrench. Do not use pliers or channel locks you'll crack the plastic housing. Replace Cartridge: Remove old filter, clean housing interior, insert new FD-4615 with fresh O-ring. Tighten to Spec: Hand-tighten, then 1/4 turn with wrench. Over-tightening cracks the plastic housing. Prime System: Cycle ignition ON (do not start) for 30 seconds, 3-4 times, to refill the filter housing. Check for Leaks: Start engine, let idle for 2 minutes, inspect for fuel leaks at the housing cap. FAQ Q: Will 5-micron filtration restrict fuel flow? A: No. The
