The present invention relates to a pumping device for inflating a tube or pumping oil behind pistons in particular hydraulic fluids, such as break fluids or compressed air. The systems use an electro hydraulic pump, a hydraulic hose and pistons or an air compressor and an air tank. The pumping device can run on a hydraulic or on a pneumatic system. These systems have space to accommodate hydraulic fluid or compressed air and are connected to the hydraulic pump or tank. The electro hydraulic pump is connected to the hydraulic piston unit by a hydraulic hose. A center post mounted behind the door latch supports the electro hydraulic piston unit. The air compressor is connected to the air tank by an air hose. The air tank is connected to the tube unit by an air hose, which is supported by a center post behind the door latch. Both the hydraulic and pneumatic systems comprise a front impact sensor mounted on the front bumper of the vehicle and a rear impact sensor mounted on the rear bumper and an electrical switch. Both the hydraulic and pneumatic systems comprise a control switch, which can be mounted on the door handles or on the dashboard. The switch can only be activated by an impact. Then a passenger can trigger the system by pulling the handle or pushing a button on the dashboard.
