Waste Oil Heater Forum - Your definitive source for burning waste oil for heat.

Is anyone familiar with the Logic’s new “Junior” EL75H?  I’m interested in plumbing some sort of system that auto fills the internal 10 gal tank from a 55 gal drum.  Has anyone done this?  Right now I have a hand pump in the drum with a hose going into the internal tank.  The filter screen in the fill tank builds with sludge very quickly making it very slow to fill the tank.  Any recommendations on how to filter the oil prior to reaching the screen?
