The Guarany Big Sucker is a totally new tool for home and farm. Use for all those times you want to get liquid out of something where you can not simply tip it upside down and pour it. Or where pouring it into a bottle or narrow-neck container is not practical. When the liquid is suctioned out, the valve can be reversed and the liquid pumped out again into a required container or bottle. This device may have many household and farm uses: suction oil from mower or motor bike for transfer to a waste container, suction boat bilge, suction boat engine oil, transfer of chemical from a too-heavy-to-pour drum, suction sink s-bend before disconnecting, etc, etc. We are sure you will find many uses. Pump is resistant to all regular oils and chemicals. Full instructions supplied.
