X15 fuel not priming

[Maksdriver]

Hello guys, I’ve been surprised today. Truck is Kenworth T680 Cummins X15. After changing fuel filters (as usual, just regular PM) fuel system stop priming. Fuel filter Fleet guard FF5825NN, fuel water separator Paccar K37-1021, I always install that filters, bought from official stealership kenworth. Electrical fuel pump works like usual (I hear the sound), but after several cycles both filters is dry. No fuel at all. Any suggestions? Thanks in advance.
