Ground support service cart apparatus and methods

An equipment service cart, comprising:

• a support frame;
• at least two axles mounted to the support frame;
• at least one pair of wheels mounted to each axle;
• a tow bar connected at one end of the support frame and configured for attachment to a powered vehicle to tow the equipment service cart;
• a fuel tank;
• a pump system configured to add fuel to and remove fuel from the fuel tank, the pump system including a fueling nozzle, a fueling hose, a defueling nozzle, and a defueling hose;
• a fuel valve assembly operable to control fuel flow into and out of the fuel tank and including fuel valve controls;
• a container storage portion configured to retain a plurality of removable fluid storage containers;
• at least one DC power source;
• a power control system operable to control power from the at least one DC power source as a sole source of power to operate at least the pump system and the fuel valve assembly;
• wherein the container storage portion, the power control system, the fuel valve controls, and the fueling and defueling nozzles are consolidated at one end of the equipment service cart at a centralized control location;
• said centralized control location being spaced rearward of the wheels for access by an operator at the centralized control location on the equipment service cart to provide efficiencies of time for the operator and to facilitate servicing activities by the operator in close proximity to the equipment being serviced using the equipment service cart.
