All 100% billet construction... This regulator features a Viton 3-layer diaphragm rated at 100 psi constant and 300 psi burst. It is totally adjustable from 30 psi to 100 psi. Like our previous design, it also has a separate port for the vacuum line. This allows for easier adjustment without having to remove your vacuum line each time. It is a direct bolt-in replacement for your stock regulator.
By installing an adjustable fuel pressure regulator, it will enable you to tune your car to the way you want it to respond. It is also one of the first upgrades you need to make to increase fuel delivery.
