This is the new upgraded fuel pressure regulator kit from Ford for their E-series 6.0L with an upgraded spring. The fragile 6.0 injectors are damaged by any pressure below 45 psi. The original stock pressure regulator sets fuel pressure at 50 psi. This does not leave much room for pressure drop due to hard engine demand. If you are running a programmer on your truck, you may want to consider installing this simple modification to help supply the engine with the fuel it is requiring for more power.
