It supports gasoline and alcohol blends (E85) and installs in bypass\/return-style fuel systems to stabilize pressure for high-performance or modified engines. The regulator’s top-mounted adjustment screw and included gauge make tuning straightforward while multiple included adapters speed installation to many fuel rails.\u003c\/p\u003e\n\n\u003ch3\u003eHow do I adjust the fuel pressure and read the gauge?\u003c\/h3\u003e\n\u003cp\u003eAdjustment is done via the set screw on the regulator’s top; turn to increase or decrease pressure and monitor the included gauge to reach your target PSI.
