OM603 fuel pressure

Hi, i have a question about my S124 Om603, the issue is when leave the standind for overnight the fuel from my prefilter runs out, and when i start the car in the morning it takes longer to start because it has to pump the fuel up, i've cleaned my fuel trainer and changed both of my fuel fiters and bled the system several times and i can't seem to understand what's causing this issue, i've noticed that it gets worse when the weather is cold, anyone has any ideas what could cause this issue ?
