This is the new upgraded fuel pressure regulator kit from Ford. 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.
By installing this kit fuel pressure will be raised to 60-65 psi. Most engines will perform a little better and injector life will be extended.
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.
- Upgrade your factory fuel pressure spring and get 5-15 More PSI
