They are precision machined from 6061-T6 billet aluminum for strength and durability. These regulators are adjustable from 4-65 psi and will handle both carbureted and EFI applications. A second pressure spring is included allowing you to increase the fuel pressure range up to 65 psi for EFI systems. They have 6AN port sizes to adapt to your new or existing fuel lines. So, if you are currently running a carbureted system but plan to upgrade to EFI in the future, these regulators will have you covered either way.\n\nThese kits include a fuel pressure gauge and adapter fittings to get you started on your installation.\n\u003ch3\u003eFeatures:\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eAdjustable from 4-65 psi for precise fuel pressure adjustments\u003c\/li\u003e\n\u003cli\u003eConstructed of billet aluminum with a black anodized base and a clear anodized top for good looks\u003c\/li\u003e\n\u003cli\u003eUsed in systems with a return line back to the tank\u003c\/li\u003e\n\u003cli\u003e(1) 6AN O-ring Inlet; (1) 6AN O-ring Outlet; and (1) 6AN O-ring return\u003c\/li\u003e\n\u003cli\u003eIncludes fitting for manifold reference\u003c\/li\u003e\n\u003cli\u003eIncludes an 1\/8 NPT gauge port\u003c\/li\u003e\n\u003cli\u003eBoost Reference - 1:1\u003c\/li\u003e\n\u003cli\u003eThe 4-15 psi carbureted spring comes installed in the regulator\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eProduct Specifications:\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eProduct Details:\u003c\/strong\u003e Carb\/EFI adjustable billet by-pass return style fuel pressure regulator 6AN Kit with Fuel Pressure Gauge and Adapter Fittings\r\nBoost Reference - 1:1\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAdjustable:\u003c\/strong\u003e Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eColor:\u003c\/strong\u003e Black\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFuel System:\u003c\/strong\u003e EFI\/Carb\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFuel Type:\u003c\/strong\u003e Gasoline\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eGauge Port:\u003c\/strong\u003e Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eGrade Type:\u003c\/strong\u003e Performance\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInlet Quantity:\u003c\/strong\u003e 1\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInlet Size:\u003c\/strong\u003e 6 AN O-Ring\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInlet Type:\u003c\/strong\u003e 6 AN ORB\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial:\u003c\/strong\u003e Aluminum\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMounting Hardware Included:\u003c\/strong\u003e Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMounting Type:\u003c\/strong\u003e Inline\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOutlet Quantity:\u003c\/strong\u003e 1\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOutlet Size:\u003c\/strong\u003e 6 AN O-Ring\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOutlet Type:\u003c\/strong\u003e 6 AN ORB\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePart Type:\u003c\/strong\u003e Fuel Pressure Regulator\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePort Quantity:\u003c\/strong\u003e 3\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eProduct Type:\u003c\/strong\u003e Fuel Pressure Regulator\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eReturn Size:\u003c\/strong\u003e 6 AN O-Ring\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStyle:\u003c\/strong\u003e Bypass\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Holley","offers":[{"title":"Default Title","offer_id":49710078984430,"sku":"HLY-12-880KIT","price":285.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0819\/9110\/6798\/files\/d107c0582cac5bbae4a9148676157c265cfd51e6.jpg?v=1791514193","url":"https:\/\/elmosspeedshop.com\/products\/holley-carb-efi-adjustable-billet-by-pass-regulator-6an-kit-12-880kit","provider":"Elmo's Speed Shop","version":"1.0","type":"link"}
