Prius gas overflow

Driving it was the right thing to do. You want to burn off some of the excess gas. The real danger is overfilling, closing the cap, and letting everything expand in the heat.

Your car should be fine.

If no warning lights then no worries. If the car will be sitting and getting warm in the sun then one may consider loosening the gas cap and then tightening it later after driving some distance. Good luck!

 

It wont do any damge, the best thing to do is to drive it straight away. Like qbee said, drive about 5 or 6 miles and it will use about a pint, and that's enough space to handle any expansion that may later occur.

You know ajbdiaz, that almost exactly mirrors an experience I had late last year. The pump was running super slow and it was taking ages to fill. Same as per your situation, the pump never cut out and fuel filled right over the top and went everywhere.

My theory was that the pumps filter was probably clogged, which is the most common cause of a very pump slow. The problem is that the cut off mechanism works on back-pressure, and the slower it's pumping the less is the back pressure.

 

It happen to me too recently with my 2013 gen 3 prius and when it does. I notice my prius fuel level got stuck at full and the gas spilled out from the bottom.
