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*Double check valve design, faster flow rate, good operation of two-way check valve, quick oil output*Increase the oil-resistant rubber sphere to absorb more water and fine grain design, anti-slip and anti-aging*Thickened PVC pipe has long service life*A variety of models are applicable, trucks, cars, motorcycles and other models can be used*Instructions for use:The correct way to use the suction pump is to stretch a tube into the liquid you need to pump, and first force itSqueeze the flat rubber ball to expel the air, then immediately block the outlet of the tube with your thumb, release the rubber ball, etc.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.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.Directions are used from top to bottom. When using, keep the position of the rubber ball as low as possible.*Note: The following conditions must be met to extract the fuel tank of the car:1. There is no anti-theft oil filter in the fuel tank2. The pipe should be inserted into the fuel tank when pumping oil3. The height of the fuel tank must be higher than the height of the oil drumSpecifications:Frequently used as a hand pump in boats for fuel supply to the out-board engine.Fast and Easy handling.Works on the vacuum principle.For Transfer of Liquids as Gasoline, Diesel, Oil, Water etc.Material: PVC, Rubber, CopperQuantity: 2 * pipes, 1 *pumpPipe length: 1.5 M/2MOptionalPipe diameter: 16mm inner diameter, 20mm outer diameter Package Included:1*Oil Transfer Pump KitsOptional as shownNotes:Note: Please allow 0.1-0.3cm differences due to manual measurement, thanks.Please understand because of the light irradiation or computer display difference, so I can't guarantee photos and real color is 100% the same.Specifications:Frequently used as a hand pump in boats for fuel supply to the out-board engine.Fast and Easy handling.Works on the vacuum principle.For Transfer of Liquids as Gasoline, Diesel, Oil, Water etc.Material: PVC, Rubber, CopperQuantity: 2 * pipes, 1 *pumpPipe length: 1.5 M/2MOptionalPipe diameter: 16mm inner diameter, 20mm outer diameterPackage Included:1*Oil Transfer Pump KitsOptional as shown
