This configuration works well on either the inlet or return side of the fuel rail. A line needs to be
constructed from the filter to the rail on the inlet side of the fuel rail. On the return side of the fuel rail,
a line needs to be made from the rail to the remote mounted regulator (AEM P/N 25-302), and from
the regulator’s outlet port to the vehicle’s fuel return line.
