This billet fuel rail kit is designed for use with BTR Equalizer and Trinity intake manifolds (including compatible LT1/LT4 or LS manifold applications) where port-injection fuel rails are required. The kit includes billet 6061-aluminum fuel rails, mounting brackets, and hardware to accommodate various fuel injector heights. Each rail features -8 AN O-ring boss ports for reliable fuel delivery under stock or high-performance fuel pressure. The kit is suitable for performance builds, upgraded fuel systems, or any application requiring durable, high-flow fuel rails for EFI systems.

BTR BTRFRK01 Features:

• Fitment: BTR Equalizer and Trinity intake manifolds — compatible with many LS / Gen-V (and other) EFI engines using port injection.
• Construction: Billet 6061-aluminum fuel rails for strength and consistent fuel flow under pressure.
• Fuel Ports: -8 AN O-ring boss openings on both ends, suitable for aftermarket or high-pressure fuel systems.
• Includes mounting brackets and hardware — accommodates a wide range of fuel injector lengths/heights without custom fabrication.
• Ready for high-performance applications: suitable for boosted, high-HP, or otherwise demanding fuel delivery requirements.

BTR BTRFRK01 Includes:

• Pair of billet fuel rails
• Mounting brackets
• All necessary installation hardware
• Fuel fittings (for AN / ORB plumbing) as supplied by manufacturer

BTR BTRFRK01 Notes:

• Intended for use only with BTR Equalizer or Trinity intake manifolds (or compatible aftermarket manifolds matching their port/injector layout)
• Verify injector height/length before installation — if using long/truck-style injectors, additional bracket kit (BTR part BRKT-02) may be required for proper mounting
• Sold as a complete kit — one kit needed per intake manifold installation
• Recommended for high-flow or high-pressure fuel systems, but also suitable for stock fuel systems that use port injection
