I was thinking, I know that 3/16" line has 2 psi of resistance per foot. So does this mean that when I am figuring out what psi to force carb at for a given Co2 volume, I need to factor that gas line length in?

Ex.
38 degrees
2.5 volumes of Co2
=11psi

With 2 feet of gas line from the regulator to the keg, would I need to increase that pressure by 4 to accurately get that specific volume of Co2? (2psi*2ft= 4 psi)

I'm pretty sure when people talk about resistance per foot, it's beverage line. The gas line length doesn't matter.

I understand that and agree. But that line has to pose some sort of restriction doesn't it?

I don't think it does, it's equal from start to finish since it's pushing nothing but itself, and as a gas it has no (or super little) weight/resistance.

The gas line only restricts flow rate not pressure. The pressure will equalize and be the same as the regulator setting.
