I know there is a pressure differential sensor under the battery at the fuel tank. Could this be not working properly?

In my reading, it seems this could indeed be the culprit.  
However: are we sure the fault code is real?  By that I mean, are we sure you have a leak? Or is it possible you have a sensor issue?  Do you hear hissing when you remove the gas cap at the fill station?  Do you smell gasoline when the car is running? 
I assume you've cleared the code since replacing all of those items, and it's returning immediately?
