Here is the tank. It is alot smaller than I thought it would be. 3 Gallons should last quite awhile. I had to change out the fitting at the pump to a 3/8 NPT to 4an so the hose I made would hook right up to it. It came with push style fittings to accept nylon hose. When inspecting the inlet hose to the pump I noticed that their factory fitting was pretty loose at the tank so I took it apart and tightened it up.
