That red hose is the air outlet for the pump.

I just run it down along the frame to the lower control arm area.

If you are on gas or using it on the street it might not be a big deal where you run it to but I was concerned if it blew some moisture out on alky, where I ran it.

That tank is a moroso breather tank that I chopped up and modified into a catch can.

If you run on gas and had your valve covers baffled good you and didn't suck any oil into the pump you could go from the valve covers through the pump and put a breather tank on the outlet of the pump.

Moroso 85470 would work for that.
