Get a drum. I had a friend at a dealership save me a 55 gal that had windshield washer fluid in it. Ideally I would rather have had a smaller one. Ask around and you might get one for free like I did.
I used an old steel kitchen sink. Use the drain too. I took a piece of screen wire over the bottom in case any small parts were to find their way to the drain. All free.
I added a flash lid. Just a piece of sheet metal hinged.
Get about 4 ft of 3/8" vinyl tubing.
The rest you can figure out. Mounting of the sink, rigging a spout.
