ABSTRACT:
A lift as a personal tool used manually to lift portions of a fuel hose successively, equipped to slide along the fuel hose as a user walks erect as the user moves along the fuel hose progressively causing residual fuel in the fuel hose to drain out the hose distal end, away from the fuel truck. The lift includes a handle adapted for grasping by its user separated from a fuel hose support by a bar depending from the handle forming a C-shape with an open portion opposite the bar and a trough opposite the handle. A roller disposed to roll on the hose support has a radially extending flange on each roller end maintaining the fuel hose central on the roller. In use, the user walks in erect posture from the truck along the fuel hose with the lift hanging from the user's downwardly extending arm. As the hose leads to the ground and before the hose reaches the ground, the hose moves into the lift trough engaging the hose at a hose engagement level several inches above the ground. As the user continues to walk slowly along the hose, the lift lifts the fuel hose in successive portions along the fuel hose progressively urging fuel in the hose to move forward of the lift by gravity while hose portions rearward of the lift, that is, toward the truck, fall to the ground empty of fuel.
