Method for autonomously fueling machinery operating at fracking sites. A fuel tank with a plurality of fuel lines individually coupled to a fuel tank are used. Pumps are connected to some of the fuel lines. Pump outputs are coupled to hoses extending to machinery tanks to be refueled. A cap is detachably connected to the hoses and machinery tanks to be fueled. The fuel tank includes an intake filter capable of blocking approximately 10 micron contaminants with about 250 gallon per minute flow rate. The methodology of the present invention includes measuring the duration of machinery tank fuelings and the interval between fuelings. A first alarm is generated if the duration of fuelings is longer than a first interval. A second alarm is generated if the interval between fuelings is longer than a second interval.

A fluid dispenser system is disclosed herein that is configured to switch between an open position in which fluid flows through a fluid channel and a closed position in which fluid is prevented from flowing through the fluid channel. The fluid dispenser system includes a valve disposed along the fluid channel and configured to move between the open valve position and the closed valve position, a trigger actuatable between an open trigger position and a closed trigger position which move the valve between the open valve position and the closed valve position, a trigger latch configured to move between a latched position in which the trigger latch fixes the trigger in the open trigger position and an unlatched position in which the trigger latch does not constrain movement of the trigger, and a solenoid with a solenoid pin. The solenoid is configured to translate the solenoid pin between an extended position capable of retaining the trigger latch in the latched position and a retracted position that allows the trigger latch to move into the unlatched position.
