Genuine Motorcraft filtration for the legendary 7.3L Powerstroke. The Motorcraft FD-4596 is the OEM fuel filter for 1999–2003 Ford Super Duty trucks equipped with the 7.3L Powerstroke diesel — the industry standard replacement that maintains the fuel system integrity of one of Ford's most beloved diesel engines.

The 7.3L Powerstroke is a mechanically injected system where fuel cleanliness is paramount to injector longevity and performance. Genuine Motorcraft filters are engineered to the precise micron rating and flow characteristics specified for the 7.3's fuel system, effectively removing water, particles, and contaminants that cause premature injector failure and reduced performance. Using OEM-spec filters rather than aftermarket alternatives ensures the correct filtration efficiency and flow rate for reliable operation throughout the replacement interval.
