System and method for evacuating liquefied petroleum (lp) gas from a fuel distribution system

A method for evacuating liquefied petroleum (LP) from a fuel distribution system that supplies fuel from a fuel tank having an outlet port to an engine of a vehicle, wherein the fuel distribution system includes an engine supply line and a fuel rail, the method comprising:

• closing an isolation valve that is located in the fuel distribution system to isolate at least a portion of the fuel distribution system from fuel stored in the fuel tank;
• connecting a fuel evacuation system to a fuel discharge valve disposed in the isolated portion of the fuel distribution system;
• and
• removing, through the fuel discharge valve, fuel from the isolated portion of the fuel distribution system to a storage tank disposed outside of the vehicle.

A fuel system for a vehicle, comprising:

• a fuel tank configured to store liquefied petroleum (LP) fuel, the fuel tank comprising a tank outlet port;
• a fuel distribution system configured to supply fuel from the fuel tank to an engine, the fuel distribution system comprising:
• an engine supply line coupled to the tank outlet port, and
• a supply pump coupled to the engine supply line for driving fuel flow from the tank outlet port of the fuel tank to the engine;
• and
• a fuel discharge valve coupled to the supply pump for removing fuel from the engine supply line.

A vehicle comprising:

• an engine;
• a fuel system, the fuel system comprising:
• a fuel tank configured to store liquefied petroleum (LP) fuel, the fuel tank comprising a tank outlet port;
• a fuel distribution system configured to supply fuel from the fuel tank to the engine, the fuel distribution system comprising:
• an engine supply line coupled to the tank outlet port, and
• a fuel rail disposed on the engine and coupled to the engine supply line;
• and
• a fuel discharge valve disposed on the fuel distribution system for removing fuel from the fuel distribution system to a storage tank disposed outside of the vehicle.
