Ford Engineer That Designed Gas Tank Indicator Passes Away

James Moylan is most well-known for the Moylan Arrow, which stems from one rainy day in 1986, when he pulled a company car into a gas station to refuel it - only to discover that he parked on the wrong side of the pump. Moylan wound up getting soaked, which set of a proverbial light bulb - what if cars had an arrow near the fuel indicator gauge as a quick, visual reference to inform drivers which side is used to refuel?

“I got back to my office after the meeting, and without even taking my coat off, I sat down and started writing the first draft of this proposal,” Moylan told Design News in 2020. “I typed it up and turned it in and forgot completely about it." "The indicator or symbol I have in mind would be located near the fuel gauge,” Moylan wrote in his proposal to his boss, R. F. Zokas, “and simply describe to the driver on which side of the vehicle the fuel fill door is located.” By 1989, the Moylan Arrow began showing up in Ford vehicles, and the rest, as they say, is history.
