Holley EFI 534-210 LS Hi-Flow Fuel Rail Kit with Hose and Fittings

The Holley EFI 534-210 LS Hi-Flow Fuel Rail Kit is engineered to deliver maximum fuel flow for high-horsepower LS engine applications. Compatible with LS1, LS2, LS3, LS6, and L99 factory intake manifolds, this complete kit provides everything needed for a professional fuel system upgrade.

Key Features:

• 5/8-inch diameter fuel passage provides exceptional flow capacity for demanding performance applications
• Fuel rails are precision-machined to accept -8 (3/4-16) O-ring fittings for secure, leak-free connections
• Includes four -6 to 3/4-16 O-ring adapters for flexible installation options
• Complete with 6 feet of braided stainless steel fuel hose for professional routing
• Includes four 90-degree and two straight -6 AN hose ends for versatile plumbing configurations
• Bright dip black anodized finish with laser-etched EFI logo resists corrosion and maintains a show-quality appearance

This kit is the same as part number 534-209 but includes the additional braided hose and AN fittings, making it a complete solution for builders who need both rails and lines. The oversized fuel passages eliminate flow restrictions that can starve high-output engines, while the anodized aluminum construction provides durability and heat resistance. Perfect for naturally aspirated, supercharged, or turbocharged LS builds requiring reliable fuel delivery.
