2023 HDUV definitely does not. I was filling mine from my gravity tank and had engine running, when it overflowed right on exhaust tip. Fortunately it was diesel and exhaust tip spark arrestor was in place, and exhaust still cold, as I had just started it up and pulled it out of building and straight up to gravity tank to fill. I got lucky. Lesson is to make sure engine is off and watch and listen carefully. Fuel gage is way too slow to use as it does not register nearly fast enough. Any overflows dump directly on exhaust tip.
