Built for compatibility with gasoline, E85, ethanol and methanol (not diesel), the regulator offers a broad adjustment window, durable fittings, and a bypass return design to keep pressure steady under changing load and RPM conditions.\u003c\/p\u003e\n\n\u003ch3\u003eHow does the regulator control fuel pressure during tuning?\u003c\/h3\u003e\n\u003cp\u003eThe YEHERIT regulator uses an adjustable spring and diaphragm assembly to set outlet pressure between 30 and 70 PSI. Turning the top adjuster compresses or releases the spring to raise or lower system pressure, letting you dial in the flow your injectors need for accurate air\/fuel ratios.\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003eAdjustable range: 30–70 PSI for broad application.\u003c\/li\u003e\n  \u003cli\u003eReturn\/bypass design routes excess fuel back to the tank.\u003c\/li\u003e\n  \u003cli\u003eFine-tune via the accessible top adjustment nut without removing lines.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eWill this regulator work with my vehicle's fuel type and system?\u003c\/h3\u003e\n\u003cp\u003eThis regulator is compatible with most gasoline and alcohol-based EFI setups, including E85 and ethanol blends.
