Abstract
A system for filling a vented tank without spilling is disclosed. A fuel or similar liquid tank typically includes a filling tube and a vent tube secured thereto. A vent hole and the vent tube of the tank are in fluid communication with each other. A tube is in fluid communication with the vent hole for transporting any liquid located within the vent tube to a remote location. A vacuum source is connected to the tube. The vacuum source is adapted to draw the liquid through the tube and into a receptacle attached to the vacuum source.
