Where is the fuel rail pressure sensor 6.4 powerstroke?

The fuel rail pressure sensor on a 6.4 Powerstroke engine is typically located on the fuel rail itself, near the front of the engine, close to the fuel injectors. It is usually mounted on the driver's side of the engine, just above the fuel rail. This sensor monitors the fuel pressure within the rail and sends that information to the engine control module (ECM) for proper fuel management. For access, it may require removal of some components, depending on the vehicle's configuration.
