The plumbing. Pump output flows through an in-line heater (6500W @ 220V) then into the drum through a Rilla Biofuels' 2-Pipe Drum Port through the long tube. Pump return is through the short tube with a 90deg fitting so it draws "down" from the glycerin flow in the drum. Condenser is plumbed in the top, smaller port on the drum.
