3/4'' Multi-Purpose, Self-Priming, Pure Copper Check Valve 2 Pack by Original Safety Siphon - 5 Gallons Per Minute Flow Rate - Great for Homebrewing and Wine Making

I actually changed my star rating after using the product to transfer fuel to a vehicle from an older gas can with no spout. What a great tool to have.

Works like a charm. No more holding on to a 6 gal of diesel fueling the tractor!!

This siphon works great and pulls a lot of volume. It needs 3/4 inside diameter tubing which my not fit in car gas tanks. I use it to fill tractors, skid loaders, and drain stock tanks. Highly recommend.

Several years ago I got gasoline in my lungs while siphoning gas from a barrel. These check valves are easy to use and make an unpleasant task much safer.

Picture shows 2 valves, I only received one! $9.58 / item ???I will return and order from someone that is honest!
