Holley 534-209 - Holley Billet Aluminum Fuel Rails for OE-Style LS Engine Intakes

These billet aluminum fuel rails make a great addition to any GM LS1, LS2, LS3, LS6, or L99 engine bay. They are direct bolt-on rails for OE-style intake manifolds and are machined from solid aluminum with the undersides relieved for ultimate weight savings. The aluminum is finished in a high-gloss anodizing making it both durable and good-looking. Fuel rail kits come with matching hand-polished fittings and a stainless braided hose. Both the fuel rail set and kit come with -6 to 3/4-16 O-ring adapters but are machined to also accept -8 O-ring fittings (available separately) to fully take advantage of the 5/8'' diameter fuel passage.
