i cant say for sure about pulling it out of the tank but those lines are thicker, they primary reason for heating i thought was to heat it for the motor. maybe some people with more experience heating WVO can chime in.
mankypro - i have heard that those little heaters are a great way of heating things up before they hit your engine. i haven't used one myself just passing on what i have heard. that and since it is electric you don't have to worry about your engine warming up.
which leads to another point. it might be easier to wire up a pad heater and faston it to the bottom of your tank instead of piping coolant back there.......
