That sucks.

How many miles/hrs do you have?

What fuel filters have you pulled OUT of the system?

Try one of these: New Intank 30mm Fuel Pump 2009 2013 Husaberg KTM 390 450 570 81207088011 | eBay

Still on the original Fuel pump on my FS 570 and just hit 7100km's on the bike..you must be really unlucky?

I only have a fuel filter in the tank. None added and none taken away. I think it's a perfect storm of heat and humidity in Florida combined with Ethanol.
