Non return valve

Can anyone post a link to a good non return valve for my flat tank im having to keep bleeding it due to hills when tank gets low ?

I'm not sure that would work. They are designed for fluids and when you are driving around low. A little bit of air would still get in, you could try an air one that may work.
