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 are offered with two port sizes, 3\/8\" NPT or 6AN 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.\u003cbr\u003e\u003cbr\u003e\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eFeatures:\u003c\/strong\u003e\u003c\/p\u003e\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\u003cp\u003e\u003c\/p\u003e\u003ch3\u003eApplication:\u003c\/h3\u003e\u003ctable\u003e\u003ctbody\u003e\n\u003ctr\u003e\n\u003cth\u003e\u003cstrong\u003eYear\u003c\/strong\u003e\u003c\/th\u003e\n\u003cth\u003e\u003cstrong\u003eMake\u003c\/strong\u003e\u003c\/th\u003e\n\u003cth\u003e\u003cstrong\u003eModel\u003c\/strong\u003e\u003c\/th\u003e\n\u003cth\u003e\u003cstrong\u003eSubmodel\u003c\/strong\u003e\u003c\/th\u003e\n\u003cth\u003e\u003cstrong\u003eEngine Size\u003c\/strong\u003e\u003c\/th\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\u003ctd\u003eUniversal\u003c\/td\u003e\u003c\/tr\u003e\n\u003c\/tbody\u003e\u003c\/table\u003e\u003cp\u003e\u003c\/p\u003e\u003ch3\u003eSpecs:\u003c\/h3\u003e\u003ctable\u003e\u003ctbody\u003e\n\u003ctr\u003e\n\u003cth\u003eBrand\u003c\/th\u003e\n\u003ctd\u003eHolley\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eColor\u003c\/th\u003e\n\u003ctd\u003eBlack\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eEmission Code\u003c\/th\u003e\n\u003ctd\u003e5\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eFuel System\u003c\/th\u003e\n\u003ctd\u003eEFI\/Carb\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eFuel Type\u003c\/th\u003e\n\u003ctd\u003eGasoline\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eInlet Size\u003c\/th\u003e\n\u003ctd\u003e6 AN O-Ring\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eMaterial\u003c\/th\u003e\n\u003ctd\u003eAluminum\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eOutlet Size\u003c\/th\u003e\n\u003ctd\u003e6 AN O-Ring\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eProduct Type\u003c\/th\u003e\n\u003ctd\u003eFuel Pressure Regulator\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eReturn Size\u003c\/th\u003e\n\u003ctd\u003e6 AN O-Ring\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eStyle\u003c\/th\u003e\n\u003ctd\u003eBypass\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eWarranty\u003c\/th\u003e\n\u003ctd\u003eLimited 90 Day\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\u003c\/table\u003e","brand":"Holley","offers":[{"title":"Default Title","offer_id":32587476041777,"sku":"12-880","price":179.95,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/2493\/0960\/files\/adjustable-billet-by-pass-regulator-6an-12-880-modern-day-muffler-1.jpg?v=1738925808","url":"https:\/\/moderndaymuffler.com\/products\/adjustable-billet-by-pass-regulator-6an-12-880","provider":"Modern Day Muffler","version":"1.0","type":"link"}
