Great product

Great priduct easy installation.

Great service and fast shipping !

The customer service was Friendly, product was exactly wat I needed and shipping was fast !

Good quality and fit. Easy to install and setup.

This kit comes with everything you need to setup an adjustable fuel pressure regulator. It helps when diagnosing problems to insure you are at the right fuel pressure, especially when tuning and dealing with upgraded injectors. My only complaint is the pressure dial that attaches to the regulator is impossible to get straight. It holds pressure so you have to screw it in tight, but doing so always causes the face of the dial to be off center. It would be great if the face could rotate separately to make it align properly. It doesn't affect the operation, just triggers my OCD.


Great kit to upgrade when going with a high pressure pump

This regulator is a must for anybody upgrading their fuel system.
