Mine is all done in 3/8 hvac copper and ptc fittings it will sit all the way up for weeks, no leaks at all. 3/8 is dang near as easy to work with as 1/2" dot and my truck still moves super quick.

        if you want something that looks better we use aluminum fuel line on many set ups. it is easy to work with and you can polish it up as well
