FUEL FILTER F/6L FORD

Fuel filter kit for Ford 6.0L Powerstroke truck applications. This kit replaces part number PFF4604. Fuel filters used on Ford 6.0L engines now have an improved fuel filter seal design.
This new design ensures that high differential pressure due to poor quality fuel or new biodiesel blends will not compromise the filter performance. The new filter design is an improvement. Both the old and new style filters are functional and approved for use by the Ford Motor Company.
