It had a start routine that included running the electric pump on the starter circuit then switching over to a relay that was powered through the oil pressure switch. If you don't have oil pressure you don't have fuel after you let off the starter. I found out about it by inadvertently knocking the oil pressure sender wire off during my first oil change on the car, but that's a story for another forum/day.
A stuck float would have shut off the fuel pump when the motor quit. Any other loss of oil pressure would do the same when the carbs run dry. Not bad insurance and a very simple circuit to add.
I had a new '73 Vega GT. When I lived in Idaho in the '70s we got temperatures down to -20?F. The engine oil would go so thick I had no oil pressure first thing in the morning. I'd start the engine and it would run until the fuel in the float bowl was exhausted then the engine would die. I'd go back into the house for a few minutes and then try again when the residual heat warmed the oil enough for the pump to provide pressure. There was no oil pressure gauge so at first I didn't know if it was a faulty switch or light. I soon took the following corrective/preventive measures. I installed a pressure gauge which confirmed the lack of pressure. I installed a water heater spliced into the car's heater hose. I converted to Eon (now Neo I believe) fully synthetic engine oil. A side benefit of the water heater was that I had instant heat in the car when I started it on a cold morning!
