Abstract: A fuel system for a vehicle propulsion system includes a fuel temperature determination module that determines a temperature of a fuel, a fuel pressure determination module that determines a pressure of the fuel, a prime determination module that determines whether the determined fuel temperature is above a vaporization temperature on a predetermined distillation curve and the fuel pressure is below the predetermined distillation curve at the determined fuel temperature, and a controller programmed to command operation of a fuel pump in response to the prime determination module determining that the determined fuel temperature is above a vaporization temperature on the predetermined distillation curve and the fuel pressure is below the predetermined distillation curve at the determined fuel temperature.
