CNC-machined from 6061-T651 aluminum, it accepts an AN8 feed and AN6 return, offers a vacuum\/boost reference, and comes with a calibrated 0–160 PSI gauge. The unit is designed as a return-style regulator for systems that recirculate excess fuel back to the tank and works with many gasoline and E85 applications when installed correctly.\u003c\/p\u003e\n\n\u003ch3\u003eHow does this regulator adjust fuel pressure for EFI and E85 engines?\u003c\/h3\u003e\n\u003cp\u003eAdjustment is done with the top adjustment bolt, allowing precise control within the regulator’s working range.
