Description: Description: *Accelerate new upgrades, seal well and save effort, thicker 20mm diameter, faster flow rate and double stop valve oil pump, pumping only takes 5 seconds _x000D_ *Double check valve design, faster flow rate, good operation of two-way check valve, quick oil output _x000D_ *Increase the oil-resistant rubber sphere to absorb more water and fine grain design, anti-slip and anti-aging _x000D_ *Thickened PVC pipe has long service life _x000D_ *A variety of models are applicable, trucks, cars, motorcycles and other models can be used _x000D_ *Instructions for use: _x000D_ The correct way to use the suction pump is to stretch a tube into the liquid you need to pump, and first force it _x000D_ Squeeze the flat rubber ball to expel the air, then immediately block the outlet of the tube with your thumb, release the rubber ball, etc. _x000D_ The ball slowly swells and recovers. After the liquid is pumped up to fill the rubber ball, the thumb blocking the outlet is loosened. Repeated operation 1-2 times will form a continuous self-flow. _x000D_ This oil pump needs to rely on the pressure of air to achieve self-flow, because the inner diameter of the pipe is small and the flow rate is relatively slow. _x000D_ Directions are used from top to bottom. When using, keep the position of the rubber ball as low as possible. _x000D_ *Note: The following conditions must be met to extract the fuel tank of the car: _x000D_ 1. There is no anti-theft oil filter in the fuel tank _x000D_ 2. The pipe should be inserted into the fuel tank when pumping oil _x000D_ 3. The height of the fuel tank must be higher than the height of the oil drum _x000D_ _x000D_ _x000D_ Specifications: Frequently used as a hand pump in boats for fuel supply to the out-board engine._x000D_ Fast and Easy handling._x000D_ Works on the vacuum principle._x000D_ For Transfer of Liquids as Gasoline, Diesel, Oil, Water etc._x000D_ Material: PVC, Rubber, Copper_x000D_ Quantity: 2 * pipes, 1 *pump_x000D_ Pipe length: 1.5 M/2MOptional_x000D_ Pipe diameter: 16mm inner diameter, 20mm outer diameter_x000D_ Package Included:
