A fuel management method for long term stationary truck use is provided. This method includes a truck with at least a first saddle tank or a second saddle tank integral to the truck. Each saddle tank has a fuel level sensor to measure the fuel level. A fuel trailer provides supplemental fuel, and a fuel pump downstream of the fuel trailer and upstream of the truck pressurizes the fuel from the fuel trailer. The method includes supplying fuel to local users from saddle tanks, activating the fuel pump when the fuel level of both the saddle tanks is less than a first predetermined threshold, thereby transferring fuel from the fuel trailer to the first saddle tank and the second saddle tank, deactivating the fuel pump when the fuel level of either the saddle tanks is greater than a second predetermined threshold.

Data are collected on a turbidity of a fuel tank at each of a plurality of fueling stations. A fueling station is selected based on the collected data. A vehicle is moved to the selected fueling station.

An improved fill cap for delivering a fluid from a fluid transporting mechanism to a fluid tank is disclosed. A connection plate is coupled to an opening of the fluid tank and a probe is disposed within the fluid tank and coupled to the connection plate at a first distal end. The fluid flows into the fluid tank through an outlet at a second distal end of the probe. A valve is disposed at the second distal end of the probe and is movable between an open position and a closed position to control fluid flow out of the probe outlet. An arm is coupled to the valve and moves the valve between the open and closed positions and a float is coupled to the arm that moves the arm depending on the level of fluid in the fluid tank.

A multiply-redundant system that protects fueling of rockets, aircraft and other vehicles using Liquefied Natural Gas (LNG) along with an oxidizer such as Liquefied Oxygen. One or more sensors in combination with one or more optional microswitches combine to detect any leaks, fire or explosion hazards quickly locking out further fueling. For different levels of safety, different combinations of sensors can be used.

A mobile fuel distribution station includes a mobile trailer, a pump, a manifold, hoses, detachably connectable fuel caps connected or connectable with the hoses, valves, and fuel level sensors. The station is configured to operate the pump responsive to a low fuel threshold to provide fuel to the manifold, from the manifold to the valves, and from the valves through the hoses. A related method includes receiving fuel operating parameter data from at least one mobile fuel distribution station into a remote server, determining whether the fuel operating parameter data is within a preset limit, and sending a control action in response to the fuel operating parameter data being outside the preset limit. A related system includes one or more of the stations, at least one server configured to receive fuel operating parameter data, and at least one electronic device configured to communicate with the server.
