Why does my car struggle when I fill up with gas?
Potential causes include worn ignition parts (coils and spark plugs), lean condition (too much air, vacuum leak), rich condition (too much fuel, fuel presser, leaking injector) or a worn engine (carbon buildup or low compression).

How does a running engine affect fuel level?
When the engine is running, it can pull fuel from a tank with a higher level easier and return fuel easier to the tank with a lower level. So a running engine will equalize faster. They call it a dual draw system and when they are working, no crossover line is needed.
