1. A fuel system for an engine, comprising:
- a fuel line configured to deliver fuel from a removable main fuel tank to the engine;
a first control device configured to release a flow of the fuel from the removable main fuel tank into the fuel line in response to an installation of the removable main fuel tank;
an auxiliary fuel tank connected to the fuel line, wherein the fuel line is further configured to deliver fuel from the auxiliary fuel tank to the engine;
a monitoring device configured to detect a fuel pressure of the fuel system, wherein an increase in the fuel pressure is associated with the installation of the removable main fuel tank; and
a second control device configured to fill the auxiliary fuel tank with at least a portion of the fuel released from the removable main fuel tank in response to the monitoring device having detected the increase in the fuel pressure, and wherein the second control device is further configured to release the portion of the fuel from the auxiliary fuel tank into the fuel line for consumption by the engine in response to the monitoring device detecting a decrease in the fuel pressure.

Abstract
A fuel system for an engine includes a fuel line that delivers fuel from a main fuel tank to the engine and a first control device that releases a flow of the fuel from the main fuel tank into the fuel line. An auxiliary fuel tank is connected to the fuel line, and a second control device controls a flow of the fuel between the auxiliary fuel tank and the fuel line. After the fuel is released from the main fuel tank into the fuel line, the second control device fills the auxiliary fuel tank with the fuel from the main fuel tank.
