Also, keep fuel+heating line wrapped in insulation. I used foam pipe insulation wrapped in electric tape. You could probably use pool noodles wrapped in duct tape.

DO NOT use copper for WVO systems. it reacts. Use steel. I used old steel oil furnace lines.
The coolant line runs through a steel pipe going throught the bottom of the WVO tank.

My WVO tank had a 2" pipe coming out of the bottom, with a ball valve. You'd be surprised how clean you can get WVO with newspaper filters.
My newspaper filter was basically a bucket with the bottom gone, with a layer of chicken wire, screen, then newspaper sheets, and then a piece from another bucket to slide over holding the "filter" on the bottom of the bucket. Before using this filter, i used anyhting i could find to get rid of bigger particles.
