It's been nearly 20 years since last I ran a diesel (and even then only for a season). I recently got a PAW .049 from Mr. Clutton, and waiting on the fuel to arrive. I have a couple of questions;

Is it a good idea to refrigerate the fuel, then just topping off a small bottle to take to the field with me?

I understand that plastics don't do all that good of a job keeping ether in, how well does neoprene work? How about nylon? I'm toying with the idea of making a pump can so I don't have to uncap it every time I want some fuel.
