Whether upgrading for additional fuel delivery needs to run upgraded fuel lines, or to simply clean up your engine bay, ACUiTY's K-Series High-Flow Fuel Rail is the most versatile and refined solution available.

With it's 1/8 NPT port on top, -8 o-ring boss (ORB) ports on both ends and another -8 ORB port located at the middle of the rail, there are a variety of ways you can set the rail up for your car (see "Fitment Info" for application-specific fitting requirements).

Each rail is constructed from 6061-T6 aluminum and has a satin-texture, anodized finish with laser-etched technical info and logos.

Among the rails' other features, are countersunk mounting screw holes and supplied class 10.9+ hardware to replace the OEM studs. Each rail is also supplied with a stainless steel 1/8 NPT plug in case a top-mounted fuel pressure gauge is used. The end locations for the -8 ORB ports have been specifically machined to help reduce the likelihood of wrench damage to the rail's cosmetic finish during installation.

As an added bonus rarely found on aftermarket rails, the rail allows the end-user to retain the OEM injector clips if you prefer. The rail is able to be setup for a variety of applications, depending on the fittings you choose to pair with it.

Among the available fittings are plugs, 1/8 NPT adapters for side-mounted gauges or sensors, -6AN and -8AN adapters for those running braided fuel lines, and 5/16" Quick Connect adapters for those running OEM fuel lines.
