Does anyone know where you can buy a inline flapper fuel check valve?

I need one for my air vent system in my fuel tank.

A lot of diesel cars can have a retrofit one of these, usually when the valve in the filter assembly doesnt keep the fuel from running back down the line. I sell them, but that probably doesnt help you much. They come in various bore sizes from 1/4" thru to 3/8". They are also relatively cheap and made from aluminium

Any part numbers by chance?

Does it have to be a flapper or will a poppet work?

MSC has a variety of check valves.

Are those rated for gasoline?
