I bought a 1 tank system with a 55gph PAbiodiesel rig. I am trying to investigate if I should make this a two tank system for better performance? Also, I was looking into a nozzle from Utah biodiesle for dewatering. Any help, pictures or drawings would greatly be appreciated to help this WMO noob. The end result will be W85 to put in a 80-90s mercedes, of which I am on the look for.
