Fuel Rails & Kits
Fuel Rails & Kits provide the mounting structure and fuel distribution pathway for injectors in multi-point EFI systems. These precision components connect the main fuel supply to individual injectors while ensuring even pressure and flow distribution across all cylinders. High-quality fuel rails feature CNC-machined aluminum or stainless steel construction with generous internal diameters to maintain consistent pressure and minimize pressure drop during high-demand situations. Our comprehensive selection includes application-specific rails designed to fit particular intake manifolds and engine families, as well as universal designs that can be adapted to custom applications. Complete kits include the rails, mounting hardware, fittings, crossover lines, and often pressure regulators for a comprehensive solution. For high-horsepower applications, rails with larger internal volumes help dampen pressure pulsations and ensure consistent fuel delivery to all injectors. Proper rail selection should consider injector size compatibility, desired fuel line connection types, and adequate clearance within the engine compartment. Quality fuel rails not only improve performance through optimized fuel distribution but also enhance engine bay appearance with their precision-machined finish and clean installation.-
