Welcome.
I call bs on the masking of the sensor.
Sure isn't a very good marketing ploy on gm's fuel filter ability. Dealer would have to be more convincing to me.
I would want to see the fuel sample in a glass jar that they pull in front of me.
I'm thinking about the days that oil drain plugs had crush washers the needed to be replaced everytime plug was removed.
Beginning to think the babymax's plug needs replaced every time! 😁
