ABSTRACT:
A fuel rail vent system for evacuating air from a fuel rail includes a first fuel reservoir and a first fuel line extending between the first fuel reservoir and the fuel rail. A fuel pump is configured in fluid communication with the first fuel reservoir to pump liquid fuel from the first fuel reservoir to the fuel rail through the first fuel line. A second fuel line separate from the first fuel line extends between the first fuel reservoir and the fuel rail. A primer system is configured for fluid communication with the first fuel reservoir to pump liquid fuel from the first fuel reservoir to the fuel rail through the second fuel line. A second fuel reservoir separate from the first fuel reservoir is configured for fluid communication with the fuel rail downstream of the fuel rail to receive any excess liquid fuel and/or fuel vapor upstream therefrom.
