Machined from 6061-T651 billet aluminum and supplied with stainless braided hoses, multiple springs, and a 0–160 PSI gauge, the regulator is designed for durability and flexible tuning. The unit accepts AN feed and return fittings and includes a vacuum\/boost reference port to integrate with boost-referenced fuel pressure strategies.\u003c\/p\u003e\n\n\u003ch3\u003eHow does the regulator adjust fuel pressure and what parts are included?\u003c\/h3\u003e\n\u003cp\u003ePressure is changed by rotating the adjustment bolt on the regulator cap and by swapping springs to change the mechanical range. PQY preinstalls a 20–45 PSI spring and supplies both a 3–20 PSI and a 45–70 PSI spring so you can set a broad variety of target pressures without aftermarket parts.\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003eAdjustable range: 3–70 PSI (spring-dependent)\u003c\/li\u003e\n  \u003cli\u003eIncluded springs: 3–20 PSI and 45–70 PSI plus preinstalled 20–45 PSI spring\u003c\/li\u003e\n  \u003cli\u003eAdjustment via top-mounted bolt for fine tuning\u003c\/li\u003e\n  \u003cli\u003e0–160 PSI gauge included for monitoring\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eWhich fittings and ports does the kit provide for installation?\u003c\/h3\u003e\n\u003cp\u003eThe regulator uses AN-style ORB6 ports for fuel feed and return connections and an 1\/8\" NPT gauge port.
