My son-in-law does some "scrapping" on the weekends ( they have 4 kids...) and got a call from a local gas station. They had someone hit a multi unit fuel dispenser and wrecked it. The insurance co payed for a new unit, but the co that replaced it wouldn't haul the wrecked one away.
Long story short, he took it apart for scrap and gave me the 6 "explosion proof" 120v electric valves!
So the new processor I'm building will have electric control valves AND solar heat!
Just wish I had time to work on it.....................Sigh
