Machined from 6061-T651 billet aluminum with CNC precision, the regulator provides ORB6 feed and return ports, an NPT gauge port, and a vacuum\/boost reference. The package includes multiple springs to span low to high target pressures, a 0–160 PSI gauge, stainless braided AN lines, and fittings so you can install a return-style setup without sourcing extra parts.\u003c\/p\u003e\n\n\u003ch3\u003eHow does the adjustable range of 3–70 PSI work?\u003c\/h3\u003e\n\u003cp\u003eThe regulator ships with a medium spring installed (20–45 PSI) and two additional springs for lower or higher ranges. Changing the spring and turning the top adjustment bolt lets you fine-tune base fuel pressure for different injectors, pumps, or fuel types like E85. Adjustment is mechanical — no electronics — so it’s reliable and serviceable in the garage.\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003ePreinstalled spring: 20–45 PSI range for common setups\u003c\/li\u003e\n  \u003cli\u003eIncluded springs: 3–20 PSI (low) and 45–70 PSI (high)\u003c\/li\u003e\n  \u003cli\u003eAdjust via top bolt; replace spring to shift range\u003c\/li\u003e\n  \u003cli\u003eGauge port allows precise monitoring during tuning\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eWhat fittings and hose components are included for installation?\u003c\/h3\u003e\n\u003cp\u003eThe kit arrives with AN fittings and stainless braided fuel lines sized to match the regulator’s ORB6 ports and AN6 return. That reduces parts hunting and helps ensure leak-free AN connections when assembled correctly. A clear parts list in the box guides installation, but professional installation is recommended if you’re unfamiliar with fuel system plumbing.\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003eOne 6AN billet regulator with ORB6\/AN6 ports\u003c\/li\u003e\n  \u003cli\u003eSeven AN6 fittings and three stainless braided 6AN fuel lines\u003c\/li\u003e\n  \u003cli\u003e0–160 PSI pressure gauge threaded into the NPT port\u003c\/li\u003e\n  \u003cli\u003eWashers and hardware plus printed installation instructions\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eIs this regulator compatible with E85 and other fuels?\u003c\/h3\u003e\n\u003cp\u003ePQY specifies compatibility with E85, alcohol blends, and standard gasoline when proper fuel-compatible hoses and seals are used. The aluminum body and stainless lines resist many fuel types, but always verify all sealing surfaces and fittings are compatible with the fuel you run. For corrosive blends, follow manufacturer guidance and inspect fittings more frequently.\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003eDesigned for E85 and gasoline EFI systems\u003c\/li\u003e\n  \u003cli\u003eUse supplied stainless braided lines for fuel resistance\u003c\/li\u003e\n  \u003cli\u003eInspect seals and fittings for alcohol compatibility\u003c\/li\u003e\n  \u003cli\u003eRecommended: professional installation for safety and sealing\n  \u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003cp\u003eWho is this for? The PQY Adjustable EFI Fuel Pressure Regulator Hose Kit suits tuners, hobbyists, and professional builders upgrading or replacing fuel management components on EFI engines. It’s ideal when you need a return-style regulator with a broad adjustable range — from low-pressure street applications to higher-pressure race setups — and want a mostly complete kit that includes gauge, springs, and braided AN lines. If you’re converting to E85, increasing fuel flow, or building a boosted engine that requires vacuum\/boost reference control, this regulator provides the mechanical adjustability and fittings to integrate into most EFI fuel-return systems.\u003c\/p\u003e\n\u003csection class=\"product-faq-snippet\"\u003e\u003ch3\u003eFAQ\u003c\/h3\u003e\n\u003cdiv class=\"faq-item\"\u003e\n\u003cp class=\"faq-q\"\u003eQ: Can I use this regulator with E85 fuel?\u003c\/p\u003e\n\u003cp class=\"faq-a\"\u003eA: Yes.
