JEGS 555-159123 Fuel Pressure Regulator

Our universal mount billet fuel pressure regulator is ideal for turbocharged engines and will keep your fuel pressure where it needs to be when under boost. This unit includes a vacuum port you connect to your carburetor hat, and the engine vacuum will adjust the fuel pressure to the amount of boost pressure applied. An extra-large diaphragm ensures consistent pressure and eliminates issues of creep and fall-off.
