Review on 🚀 BOYISEN Siphon Pump for Gasoline - Efficient Fuel Transfer Pump with Durable Rubber Hose for Easy Oil, Petrol, Water Syphoning by Marquez Hinshaw

It should use pure gasoline in vintage cars from a gas tank. It didn't work on the third try. I tried very hard to select a quality device and it turned out to be just that. High quality rubber ball, tubing and metal fittings. The first two applications went well. After all, siphons should be easy to use. To be honest I was about to order a second one for second place. But today I had to bleed excess gas from the backup generator fuel tank and it couldn't be sucked in easily enough to create a flow. It pumped and the liquid started to flow but it took too much suction to keep the flow going so it stopped. Perhaps the inside of the valve is swollen and narrowed. Blowing out with compressed air didn't help. I don't know why, but somehow it won't work. I ended up cutting two hoses, splicing them together, and ended up using the old suction method that I was trying to avoid. Too bad. Basically good materials and workmanship. But details are important, and my information was almost useless.
