A tight roll of Glad sandwich bags, dropped down a fuel tank filler neck into a tank is another missery thing too...
bags go into fuel, electrical tape binder lets go and bags float free, truck goes driving , fuel sloshes around and a bag sucks over fuel pick up , engine quits " Hello break down service ".. suction stops when fuel pump turns off, bag floats free..
Truck gets towed seviced nothing found, nice bill to pay, drives a few k's or longer bingo picks up another bag and stops..
We pulled 40 yes 40 sandwich bags out of a tank once .. took two days to find them and cost the driver serious dollars by the end of it .
