Sure would help to make the diesel pump separate from the gasoline pumps.
Arizona's like that.Yes, some diesel handles are yellow....
I spoke to a tanker driver and asked if there were special fail safe connections for diesel or gas. Nope and he's only blown it once in 24 yrs he said.But what happen to me once on a road trip is I got 10 gallons of gas out of the green handle pump . Even said diesel on the pump. And receipt I was 500 miles from home. The 1999 5.9 had a 34 gallon tank. In a matter of a couple of minutes you could hear something was wrong. I had a guart of 2 stroke oil I dumped in. Drove a couple hundred miles add ten gallons of diesel . Barely made it home. Took out the VP 44 pump You could smell the gas on the fuel filter when I pulled it. Guy that owned the station said his dad had filled the tanks in the morning . He apparently put gasoline in the diesel tank . Funny thing is there where 40 ft motor homes filling up diesel at this station prime time tourist season Many motor homes I always sniff the hose now. The 2 stroke oil is probably the only reason I made it home
We are in the age of Woke diversity so multi colored handles are approved.Because of so much diversity in color coding pump handles, I'm initially looking for green handles, but read what the product actually is. So far, so good for me.
