Reminds me of something one of the guys in my neighborhood did to get a car, back in the '70's. He wanted a car, (IIRC it was a '55 Chevy), the car was clean and one of the nicest rides at school. The owner though was a class A jerk.

So the guy down the street put a ping pong ball into the gas tank. No problem, until you were low on gas. The ball would cut off the fuel line, the engine would die, the ball then freed up and the car would start.

The owner of the car noticed the issue, but could never resolve it, though we saw that he was working on it a lot. Finally put the car up for sale and my neighbor got it at a decent price. He did have to pull the fuel tank to fix the problem though.

“The ball would cut off the fuel line,”

I am not sure how this works ...
