It must be related to the interior shape of the gas tank, but when filling my 2021 RT, even with controlling the fuel flow to a modest level, the pump clicks off far before the tank is full. Today when putting gas in, the pump clicked itself off at 3.6 gallons added. I gently kept the pump going, holding the nozzle just barely into the tank opening. Without spilling a drop I was able to add another full gallon of gas, and probably could have added a bit more if I had been more patient. I admit that this is not an issue unique to Spyders because my former ride, a Honda Goldwing, reacted somewhat the same. Just a nuisance but on a long trip in places where gas stations are few and far between, having a truly full gas tank rather than a mostly full gas tank could be of real consequence.
