Should've listened

Older and crappy or broken/poorly repaired/modified/Jerry rigged cars also may not have functioning safety circuits or analog controls to detect and stop excess fuel such as in a crash or break down- when the engine is not running but the car is “on.”

This wouldn’t generally “flood the fuel line” and unless your fuel line was broken or seriously poorly designed or hack fixed by a total moron- fuel in a fuel line doesn’t catch fire without an external ignition source. All but impossible in a fuel injected car, VERY unlikely in a carbureted car outside perhaps some professional built dragster type cars.

HOWEVER- it IS possible on a carb’d car with the aforementioned fuel system issues or design flaws- that the fuel could continue to flow, filling the float bowls and then spilling out, where if it contacts hot exhaust etc. it could catch fire. In a car with EFI- unless there is a leak in the fuel system this is almost impossible for similar fires to start- unless you somehow had enough fuel and or manifold pressure to literally be spilling fuel back up out the intake etc- which COULD happen... but is VERY unlikely in most normal circumstances.

An engine fire from something like a clogged emission or exhaust component is feasible- especially of debris or insulation is close enough to the heat to catch fire. An oil leak or other petroleum based fuel leak could cause symptoms like poor or no acceleration- and catch fire. But yeah- the sentence “flooded the fuel line.. and caused a fire” would only make much sense of the fuel line was disconnected from the car.... even then “flooded” is not the correct term and usually refers to too much fuel inside of an engine block...

Or Mrs Maisel made the whole thing up so that people would send her tiny little digital approval messages that increase her dopamine flow.

My gut tells me.... it’s probably the second one. But... giving the benefit of the doubt.... there is room for some truth in the story, and perhaps a great deal of misunderstanding to what was happening on the part of the witnesses.
