Is the soft copper line a return oil line and where is plumb into?

Yes it is to stop pre & post nozzle drip. It goes outside to a NO 110v soleniod wired into the fan/pump motor. For now it simply drains into a 2 1/2 gallon bucket. I did have a much more elaborate system that pumped it back into the tank being 100% sealed system and using no extra pumps. problem is it used a Protek nozzle and they cant take the heat and would fail to pass oil after about a week.

I see where your flame detector is mounted and think I see where thermocoupler is placed. What's under the aluminum foil? I  like the terminal ends on the wire for easy servicing and the bleedin off of the nozzle prssure. You did a very nice job on your burner. I'd be tempted to copy your burner if mine wasn't working so well.

A nozzle change only takes 3 min because everything just unplugs and 2 wrenches to remove the flair fittings. Under the insulated foil is the fuel rail with cartridge heater. I did have plans of a 3rd revision using phanolic (sp) material for the air baffle / electrode holder. All the aluminum pulls alot of heat with the air blowing over it, the 500 watt heater runs at about 65-75% duty cycle as is. There is room to improve on the idea but i think i will go siphon nozzle for next year.
