Hello everyone, I'm mid-restore of a 1970s model Southwest ETA-1 originally manufactured for the Gulf Oil Company. The pump has two features I'd like to pick everyone's brain about. The first is in the third picture below, large arrow. The pump has this little rod that sticks out that is hooked to the lighting circuit. The switch no longer works. I'm assuming this is just a switch, but is there a chance this is a circuit breaker? Question 2, the two small holes
(small arrow) on each side of the top of the pump: was this for some type of topper? If so, would anyone know what one looked like?
Thanks is advance.
Joe
