My father owned a gas station in the 1930's and worked in the automotive trade, both before and after WWII when he served in the war. Using a measuring stick to check the tank level probably was still in practice until the 1960's, maybe even later, depending on the location. Maybe it's still done today. I'm not in that business, so I can't say.
The stick with graduate markings was used to measure however much liquid was left in the tank. Q: If there was any water in the tank, where would it be? On the top or on the bottom?
This is why he said never to fuel up when the gas truck was making a delivery.
