Abstract:
1. A fuel rail vent system, comprising: a first fuel reservoir; a fuel rail having a fuel injector; a first fuel flow path providing fluid communication between said first fuel reservoir and said fuel rail; a high pressure fuel pump configured for fluid communication with said first fuel reservoir to pump fuel under pressure from said first fuel reservoir to said fuel rail through said first fuel line; a second fuel flow path separate from said first fuel flow path, said second fuel flow path providing fluid communicating between said first fuel reservoir and said fuel rail; a primer system configured for fluid communication with said first fuel reservoir to pump fuel from said first fuel reservoir to said fuel rail through said second fuel flow path; and a second fuel reservoir separate from said first fuel reservoir, said second fuel reservoir being configured for fluid communication with said fuel rail downstream of said fuel rail.
