air hose

would a compressor air hose work for connecting the air compressor to tank. i have the s4 kit with 2 gallon tank

The air compressor line has a check valve in it, so I guess as long as you thread it in the end of the line and into the tank it should not be a problem. Make sure it is rated for the psi. I am sure Lance or someone else would have a better explanation and or recomendation

Get the steel braided lines.

Yes, a stainless steel braided hose is best for handling the high temps generated by compressing air.

i would not suggest doing this

are you referring to plastic or stainless steel?

Im pretty sure he meant plastic, running from the compressor to the tank. but I may be wrong.
