 6.4L High Pressure Fuel Pump Cover Gasket
 Some 2008 F-Super Duty vehicles with 6.4L Power Stroke Diesel engines built before August 20, 2007 may experience a check engine light on, a lack of power or no start condition. The affected vehicles have engines that were assembled using a fuel pump cover gasket that has unprotected wiring that may chafe on the fuel pump causing a grounded circuit. Read more....
New One-Piece High Pressure Oil Connector
 Since the redesign of the high pressure oil pump in 2005 and newer Power Stroke diesel engines the "snap-to-connect" or STC fitting used to connect the high pressure oil pump to the oil supply branch tube has been problematic. The two piece fittings have a tendency to flex causing wear on the seal and the locking ring resulting in leaks and occasionally the complete separation of the fitting. We have learned of a new one-piece fitting that International has begun using in production engines and as a repair part. This fitting may also find it's way into Ford parts departments as well replacing the previously released support bracket that installs over the original STC fittings which is still an effective repair.

High Pressure Fuel Lines
 The new 6.4L Power Stroke diesel engine has a high pressure common rail fuel system with a fuel pump, fuel rails and injectors mounted under the valve covers. The high pressure fuel lines that connect these components have very specific service procedures that must be adhered to prevent personal injury and engine failure. It is important to note that these fuel lines are not reusable. Read more....
Fuel Tank Contamination
 Some F-Series trucks with aft axle fuel tanks may have water and dirt getting into them through the vent mounted on top. Some fuel tanks are rusting. The rust and dirt that collects in the bottom of the tank mixes with the fuel and causes problems ranging from clogged pick up screens and filters to damaged fuel pumps and injectors. Read more....
