Fuel, communications, and power connection systems and related methods

A hydraulic fracturing unit comprising:

• a chassis;
• a pump connected to the chassis and configured to pump a fracturing fluid;
• an internal combustion engine connected to the chassis and configured to convert fuel into a power output for operating the pump;
• a system for supplying fuel and conveying electrical power associated with operation of the hydraulic fracturing unit, the system comprising:
• a fuel line connection assembly configured to be connected to the hydraulic fracturing unit and to supply fuel from a fuel source comprising natural gas to the internal combustion engine connected to the chassis, the fuel line connection assembly comprising:
• a fuel line defining an inlet end, an outlet end, and a flow path for fuel extending between the inlet end and the outlet end;
• and
• a manifold line connected to the fuel line and configured to provide flow communication between the fuel line and the gas turbine engine;
• and
• a power cable assembly connected to the hydraulic fracturing unit and configured to convey electrical power between the hydraulic fracturing unit and one or more of a remote electrical power source or one or more additional hydraulic fracturing units, the power cable assembly comprising:
• a length of power cable;
• and
• a power cable storage apparatus configured to store the length of power cable when not in use and facilitate deployment of at least a portion of the length of power cable for use.
