Manufactured by \u003cstrong\u003eHolley EFI\u003c\/strong\u003e, the aluminum rails feature a large 5\/8\" internal fuel passage and -8AN O-ring ports, giving builders the flexibility to run dual feeds, high-flow EFI pumps, aftermarket regulators, and fuels such as E85, E98, and methanol in performance LS applications.\u003c\/p\u003e\n\u003cp\u003eBoth rails can be fed independently or routed into a single high-flow fuel pressure regulator, making the system easy to configure around your fuel system layout. The black anodized billet construction, included mounting brackets, fittings, seals, and hardware make this a clean solution for naturally aspirated, boosted, off-road, racing, and custom LS builds using a compatible LS truck intake.\u003c\/p\u003e\n\u003ch4\u003eIncludes:\u003c\/h4\u003e\n\u003cul\u003e\n\u003cli\u003e(2) Holley EFI Billet Fuel Rails\u003c\/li\u003e\n\u003cli\u003e(4) -6AN to

Can I run dual fuel feeds with these rails?\u003c\/h3\u003e\n\u003cp\u003eYes.

These rails are suitable for performance fuel systems using fuels such as \u003cstrong\u003eE85 and E98\u003c\/strong\u003e, provided the rest of the fuel system—including the pump, injectors, regulator, hoses, and seals—is compatible with the chosen fuel.\u003c\/p\u003e\n\u003ch3\u003e5.
