You can pinch the hose when the liquid is close by and take out the hand pump holding the hose end in the intended container. Pump made of rubber that starts syphoning liquid immediately. Ideal for transferring gas in an emergency, a hand pump for air, water, gasoline, and other common liquids. This manual water pump can be used to replace the water in your home's fish tank as well as for fuel, petrol, diesel, gasoline, and oil. Never begin the syphoning process with your mouth open; it is very risky and very ineffective. Not suited for drinking water, salt water, or other liquids that could cause corrosion.
