According to the parts diagram your 1997 GTX should not be using the accelerator pump carbs like you have pictured above.
That being said the 1997 XP does which is the same engine so you could use the jetting and settings from that model.
You still should not be leaking fuel from the diaphragm so that definitely is an issue and could be an explosion hazard.
I know Matt Braley @Matt Braley does have the jetting information to remove the accelerator pump and run those carbs as some people just like to remove the pump and not deal with it.
You also need to get rid of all those gray Tempo lines if you haven't already.
