Plumbing a Compressor to the Tank
I am looking at taking a 5 HP pump and Motor and putting it on my Harbor Freight 21 Gallon tank. I would need to replace the copper line that runs from the compressor to the tank. What kind of copper do I need to use? Is it just that soft copper tubing from Lowes? Also would upgrading my pump and motor to 5HP give me the CFM I need to run paint guns and air sanders etc?
