if i keep it in the 3/4-full zone i will probably be good for a while until replacement. great and timely write-up!

That wear you're seeing on his old sending unit would only affect the gas gauge accuracy, it shouldn't have any affect on how the engine runs, only the pump itself and or the filter would affect how the engine runs!
