These Holley CNC machined aluminum fuel rails are designed to provide a substantial increase in fuel flow over the stock fuel rails. The ability to flow more fuel is especially important when you start building a high performance fuel-injected motor for street or race. Both universal and dedicated application designs are available from Holley for domestic and import applications, in various colors. Holley EFI fuel rails are the perfect complement to the Holley lines of high flow in-tank fuel pumps, performance fuel injectors, intake manifolds, adjustable fuel pressure regulators and high flow billet throttle bodies.
