Lifting onto a tow truck almost certainly sloshed some gas to the right lobe of the tank.

It won't last long as more fuel is sent to the left side than is consumed by the car.

When i tested mine to confirm leaking, I was expecting fast dribble but i got garden hose right into the lens of my iphone. Definitely put shop rags around the opening when you do this test.

It's interesting to see age killing the o-ring itself vs. the joint bending.
