Ford 3C3Z-9T517-AG Kit - Pressure Regulator

The Ford 3C3Z-9T517-AG is a genuine Ford Kit - Pressure Regulator, designed to maintain optimal fuel pressure. This component replaces earlier versions including part numbers 3C3Z-9T517-AE, 3C3Z-9T517-AA, and 3C3Z-9T517-AD, ensuring compatibility with updated systems. This kit is specifically engineered for use in Ford Excursion (2003-2005 with 8 Cyl 6.0L engine) and Ford F-250, F-350, F-450, and F-550 Super Duty models (2003-2007) equipped with the 8 Cyl 6.0L engine, including Diesel OHV and Turbocharged variants. It is compatible with various transmission types, including automatic (4R100, 5R110W) and manual (Tremec TR4050, M6HD-W, Z/F S6-650), and drive configurations such as four-wheel drive and rear-wheel drive. This is a stock rebuild kit and does not provide a high-flow upgrade or improve gas mileage. However, it does include the newer blue spring, a key component for maintaining proper fuel pressure at idle, cruising, and wide-open throttle. The kit also includes necessary seals and gaskets for installation, such as the seal for the cover and the main keyhole gasket.
