The Way To Use：

1. Keep the arrow on the sphere down
2. Insert the upper tube into the fuel tank
3. Insert the lower tube into the container
4. Pinch the rubber ball 3-5 times
5. Liquid outflow

Self-check Points When Siphon Pump Can't Work Normally:

1. Both of the source container and the target one are not in a sealed state.
2. Both of the hoses should be installed to the pump bulb, it can't work with only one hose installed on one side.
3. Both of the hoses are not knotted or twisted together.
4. Exhaust the gas out from the hoses before using.
5. Keep the end of the two hoses inside the containers during using, NOT just on the surface.

Please Note:

1. If the siphon pump hoses have kinks, please try to soak the kink part into a small amount of hot water for 1-3 minutes to restore it, then will not affect the use of function.
2. Never start the siphon process with mouth, it's extremely dangerous and grossly inefficient. Not suitable for drink water, salt water and any chemical & corroding liquids
