Do you store your carbs, regulators and lines?

Empty (dry) or with fuel?

It is easy to drain the carbs to help prevent residue from collecting in them as the fuel evaporates. I don't know of any advantage for draining lines.

I was just curious if being dry increased the likelyhood of all the seals and gaskets going bad.

Also worried that the fuel would eat into rubber innard of the lines.

Thanks
