The fuel line charging device was built for use in gas stations. When a gas pump is not used for a period of time, the gas flows out of the line back into the tank, creating a delay before gas exits the nozzle the next time the pump is activated. The purpose of our device is to eliminate this delay by recharging the fuel line when it has not been used for a while. It runs on a timer, and the timer is reset whenever the pump is used. When the timer reaches its limit, the pump is activated for just long enough to refill the line with fuel. The delay settings are programmable, so the time between last pump use and recharge can be customized, as well as the number of seconds the pump will run when activated to recharge the lines.
