AEM Fuel Rail Specifications

With their internal diameter of 12 mm, the AEM injection rails are particularly suitable for heavy tuning. They are equipped with a 1/8" NPT port, allowing the installation of a fuel pressure gauge (or an additional injection, like NOS).

Made in the United States, the AEM injection rails are made entirely of forged aluminum and are installed in place of the existing one thanks to the fitting accessories supplied. With their 9/16"x18 threaded inlet and outlet, they can also be used with a custom Dash 6 fuel circuit.

Their large diameter also guarantees a large fuel capacity, making it possible to dampen the pulsations and back pressure generated by large injectors. Each rail is delivered with its instructions for use, its O-rings for the injectors, and all the mounting accessories (screws, brackets, etc.).
