FAST 146035B-KIT Billet Fuel Rail Kit For Lsx And Gm Intake Manifolds - Black 92mm Ls1/ls6

The FAST 146035B-KIT is a high-flow black billet fuel rail kit engineered for optimal fuel delivery on GM LS engines equipped with LS1/LS6 or FAST LSX 92mm intake manifolds. Designed by Fuel Air Spark Technology (FAST), this kit is a direct upgrade over OEM fuel rails, providing the increased flow capacity demanded by high-performance and modified LS builds.

These billet fuel rails feature a larger internal diameter that effectively dampens fuel pressure pulses and increases fuel volume to the injectors, helping ensure consistent fueling at all RPM ranges. The result is improved fuel distribution across all cylinders and the potential for increased horsepower output.

Key Features:

• Black anodized billet aluminum construction — lightweight, high-strength, and show-quality appearance
• Larger internal diameter for improved fuel flow and pulse dampening
• Compatible with LS1 profile fuel injectors
• Designed specifically for use with GM LS1/LS6 and FAST LSX 92mm intake manifolds
• Includes black anodized rails, #8 AN fittings, mounting brackets, Super Seal, and O-rings

The complete kit includes everything needed for installation: black anodized fuel rails, #8 AN fittings, mounting brackets, Super Seal, and O-rings. Whether you're building a street machine or a dedicated track car, the FAST 146035B-KIT delivers both performance-grade fuel flow and a clean, finished engine bay look.
