The Dorman 904-204 Primary Fuel Filter Cap is a direct replacement for the worn, damaged Fuel Filter Cap on your 2003-2010 Ford 6.0L/6.4L Powerstroke. Redesigned with a hex for easier removal and installation, Dorman's Fuel Filter Cap provides a tight seal for the filter, helping to prevent fuel from leaking out of the system and therefore protecting the engine against damage. Plus, they save you time, money, and labor. Replace only the Fuel Filter Cap-instead of the entire Fuel Filter.
