Abstract: This invention is a vertical fluid storage system with an upper container connected to a lower container. A fill port can be used to fill the upper container wherein the top fill hose is in fluid communications with the upper container. A first top valve in line with the top fill hose can be included to or controlling the flow rate of fluid into the upper container from the fill port. A top fluid level sensor can be included in the upper container for sensing the fluid level of the upper container. A gravity port included in the upper container can allow fluid to flow from the upper container to the lower container either during filling or when fluid is removed from the lower container. A dispensing port can be included in the lower container for dispending fluid from the lower container through gravity of a pump.

Abstract: A portable storage unit for a fuel additive such as DEF comprising: a housing including a tray support and a cover; a container disposed in the lower area for containing a fluid; a first heating element disposed between an inner wall of the housing and the outer wall of the container; a fluid pump removable attached to the tray for pumping fluid from the container to a nozzle and for being removed from the tray to pump fluid from an external fluid source into the container; an intake hose connected to a coupler providing fluid communications between the container and the fluid pump.

Abstract: This invention is directed to a vertical fluid storage system that has a lower container for containing fluid that includes a lower fill port defined in the top of the lower container. A routing hose routes fluid from the lower fill port to an upper container disposed above the lower container. The upper container includes an upper outlet connected to a gravity hose wherein the gravity hose is connected to a gravity port to direct fluid from the upper container to the lower container. An intake valve attached to the lower container and closes to prevent fluid from flowing from the upper container to the lower container when the amount of fluid in the lower container reaches a certain volume.
