I made my own topsider, using a high temp pump designed for some industrial application, its a magnetically coupled pump and works well. I use a thick walled Teflon tube to carry oil up out of the dipstick tube and its is spliced to a lower temp hose that attaches to the pump. This contraption is of my own making, I spent about $50 on the parts and I change hot oil without any hesitation.
