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.\u003c\/div\u003e\u003ch3\u003eFeatures:\u003c\/h3\u003e\u003cul class=\"productpage_list\"\u003e\n\u003cli\u003eCarb\/EFI adjustable 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\t\t\u003cdiv class=\"brandbox\"\u003e\n\t\t\t\u003cdiv class=\"brand-content\"\u003e\n\t\t\t\t\u003cp class=\"brand-title\"\u003eAbout Holley\u003c\/p\u003e\n\t\t\t\t\u003cdiv class=\"brand-main\"\u003e\n\t\t\t\t\t\u003cdiv class=\"brand-image-container\"\u003e\u003cimg class=\"brand-image\" width=\"387\" src=\"\/\/images.holley.com\/387x\/websitebrandimages_holley.jpg\"\u003e\u003c\/div\u003e\n\t\t\t\t\t\u003cp class=\"brand-text\"\u003eHolley Performance Brands is the undisputed leader in carburetors, fuel pumps, fuel injection, intake manifolds, fuel injection, and fuel systems.\u003c\/p\u003e\n\t\t\t\t\u003c\/div\u003e\n\t\t\t\u003c\/div\u003e\n\t\t\u003c\/div\u003e","brand":"HOLLEY","offers":[{"title":"Default Title","offer_id":62137868943731,"sku":"12-880","price":207.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0897\/6289\/0099\/files\/2aa7a2045b565ef2ce7933a9465e386a07a10705.jpg?v=1767394087","url":"https:\/\/dspperformancemotorsports.com\/products\/carb-efi-adjustable-billet-by-pass-regulator-6an-12-880","provider":"DSP PERFORMANCE MOTORSPORTS","version":"1.0","type":"link"}
