🚗 Ketofa Gasoline Syphon Hose, Gas Syphon Pump for Fuel Transfer with 2 Durable PVC Hoses – Water, Liquid, Diesel, Aquarium, Pool Review

I messed up mine after one use. Gasoline leaked from one side even after it was clamped. I've used lighter pumps in the past. Will return to them.

I use it to suck rainwater out of a hollow tree. I know the hole needs to be filled, but I'm getting conflicting results from arborists.

The plunger you push to pump the liquid has an arrow on it showing the direction of the liquid as you pump it. I've used it for gas and water and it's worked great for both. You can use this siphon to transfer engine oil, but I don't recommend it because you will never pour oil out of the siphon. And if you use it for gasoline, you can't use it for drinking water afterwards. But this is an excellent siphon for water or gasoline.

The spring clamps supplied are very cheap and won't even start tightening the hose to the fitting. The rubber ball does not hold a vacuum. The factory wire wrap on each end of the socket connecting it to the test fitting and the other end is not tight at all, causing leakage. So I bought all the clamps new. It still leaks a bit because the check valve has a backflow leak, but at least it will pump now. Save some money and buy better.

This is a simple siphon with a large bulb that effectively creates a very fast siphon. I use it to drain antifreeze from my cars, but I also take it with me on motorcycle trips in case I ever run out of fuel and need help with some fuel from someone else. I think a large diameter hose CAN work with thicker oils, but I suspect this siphon - like all siphons - is best used for liquid liquids such as antifreeze, water, gasoline, etc. Good (simple) siphon.
