Fuel shut off valve

Skyport had a bunch of NOS valves.

After having my carb rebuilt, the engine runs fine but if the plane sits for days, there is still some leakage of fuel onto the cowl under the carb. I figure that the float valve just isn't quite sealing all the way and a little leakage might be a way of life for this old engine. I could stop it altogether if my main shutoff valve on the panel worked properly but in the off position, it still allows just a little fuel by and eventually, the float bowl fills and the leak becomes apparent. So, I'm just gonna replace the valve to try and deal with it because I'm tired of the smell of fuel in the cockpit when I go flying. Does anyone know a source for this valve? Univair has a listing that looks right but there's no picture and I'm sure there are different versions so I'm not sure I'd be ordering the right thing.

Thanks,
