Machined from 6061-T651 aluminum, the regulator provides a vacuum\/boost reference, a threaded gauge port, and ORB-style fittings for secure AN connections. The package supplies the most common fittings and a 0–160 PSI analog gauge so you can set and monitor fuel pressure without buying extra hardware.\u003c\/p\u003e\n\n\u003ch3\u003eHow does this regulator work with an EFI setup?\u003c\/h3\u003e\n\n\u003cp\u003eThe PQY regulator controls fuel pressure by returning excess fuel back to the tank, keeping injector feed pressure stable across load changes. You mount it inline on the fuel rail return line and connect the vacuum\/boost reference for pressure compensation. Adjustment is made by turning the top adjustment bolt to reach the desired psi range.\u003c\/p\u003e\n\n\u003cul\u003e\n  \u003cli\u003eReturn-style design uses AN8 feed and AN6 return ORB ports for secure plumbing.\u003c\/li\u003e\n  \u003cli\u003eVacuum\/boost reference port for pressure compensation under varying intake conditions.\u003c\/li\u003e\n  \u003cli\u003eIntegrated 1\/8\" NPT gauge port accepts included 0–160 PSI gauge for monitoring.\u003c\/li\u003e\n  \u003cli\u003eAdjusts roughly between 60 and 85 PSI by turning the top bolt.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eWhat fittings and components are included in the kit?\u003c\/h3\u003e\n\n\u003cp\u003eThe kit ships with the regulator body, a 0–160 PSI gauge, and AN fittings to connect feed and return lines commonly found on performance fuel systems. An AN8 cap and the necessary AN8 feed and AN6 return fittings are provided so you can install the regulator without sourcing multiple adapters.\u003c\/p\u003e\n\n\u003cul\u003e\n  \u003cli\u003e1 × PQY fuel pressure regulator (6061-T651 billet aluminum).\u003c\/li\u003e\n  \u003cli\u003e1 × 0–160 PSI analog gauge installed via the 1\/8\" NPT port.\u003c\/li\u003e\n  \u003cli\u003e2 × AN8 fittings for feed\/supply and 1 × AN6 fitting for return.\u003c\/li\u003e\n  \u003cli\u003e1 × AN8 end cap for sealing unused ports; thread sealant required (not included).\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eHow do I adjust and monitor fuel pressure safely?\u003c\/h3\u003e\n\n\u003cp\u003eAdjustment is straightforward: loosen the lock (if fitted), then turn the top bolt to increase or decrease pressure while watching the gauge. Because this regulator operates at relatively high pressure and with flammable fuels, professional installation is recommended and thread sealant must be used to prevent leaks.\u003c\/p\u003e\n\n\u003cul\u003e\n  \u003cli\u003eAdjust by turning the top adjustment bolt; range approximately 60–85 PSI.\u003c\/li\u003e\n  \u003cli\u003eMonitor fuel pressure with the included 0–160 PSI gauge during tuning.\u003c\/li\u003e\n  \u003cli\u003eUse proper AN hoses, clamps, and thread sealant; inspect for leaks before running.\u003c\/li\u003e\n  \u003cli\u003eConsider professional installation if you’re unfamiliar with fuel systems.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eWill this work with E85 or alcohol-blended fuels?\u003c\/h3\u003e\n\n\u003cp\u003eYes — the PQY regulator is compatible with E85 and alcohol blends when paired with appropriate fuel system components that tolerate those fuels. The aluminum construction and ORB\/AN fittings are commonly used in ethanol-capable setups, but seals and hoses must also be ethanol-compatible to avoid premature degradation.\u003c\/p\u003e\n\n\u003cul\u003e\n  \u003cli\u003eCompatible with E85 and alcohol-gasoline blends when paired with ethanol-rated lines and seals.\u003c\/li\u003e\n  \u003cli\u003eBillet aluminum body resists corrosion compared to some cast materials.\u003c\/li\u003e\n  \u003cli\u003eVacuum\/boost reference maintains consistent pressure across varying engine loads.\u003c\/li\u003e\n  \u003cli\u003eNot a complete fuel-system upgrade by itself; verify injectors and pump capacity.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003cp\u003eWho is this for: The PQY EFI Fuel Pressure Regulator Kit is aimed at tuners, motorsport enthusiasts, and professionals upgrading EFI fuel systems or converting to higher-flow setups. It’s a practical choice if you need an adjustable, return-style regulator with AN fittings and onboard pressure readout. Recommended for users comfortable with fuel plumbing and who will apply proper thread sealant and ethanol-compatible components; professional installation is advised if you lack fuel-system experience.\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: What pressure range can I set with this regulator?\u003c\/p\u003e\n\u003cp class=\"faq-a\"\u003eA: The regulator adjusts roughly between 60 and 85 PSI; use the included 0–160 PSI gauge to confirm settings.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"faq-item\"\u003e\n\u003cp class=\"faq-q\"\u003eQ: Is this regulator compatible with E85 fuel?\u003c\/p\u003e\n\u003cp class=\"faq-a\"\u003eA: Yes, it is compatible with E85 when used with ethanol-rated hoses, seals, and fittings; check all components for ethanol compatibility.\u003c\/p\u003e\n\u003c\/div\u003e\u003c\/section\u003e","brand":"PQY","offers":[{"title":"Default Title","offer_id":48086240723102,"sku":"B0G4V15QBH","price":49.98,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0781\/2041\/9486\/files\/pqy-regulator-front-view_2b962afa-c6e5-433b-a5fd-dfe8fa46a0b1.jpg?v=1785891429","url":"https:\/\/northtrailauto.ca\/products\/pqy-efi-fuel-pressure-regulator-kit-an8-feed-an6-return-with-0-160-psi-gauge-billet-aluminum-adjustable-vacuum-boost","provider":"North Trail Auto","version":"1.0","type":"link"}
