Just heat your vegy oil with an inline fluid heater and use some insulating wrap. Watch the HIH method, contamination both ways can occur although not prevelant on problems list. For the tank itself loop the fuel return line to oil tank instead of back to the fuel intake or use a heating pad system. I would recomend using the coolant for auxillary heat only, but about anything works. The problems arise usually from the installation process and or bouncing around giving the connections a good test of reliability. The same for your tank system. If you want it to about anything will work. This is an evolving process and you will probably change several times for your own non-kit system.
