Okay, tough 2 days for nothing. Let me explain what dumb things I've done.
First, I went to replace fuel filter, couldn't remove it, full of dirt and corrosion, had to cut it. Okay I removed it. Went to torque it, first nut okay, second one leaking. Changed washers (not sure if they'll called like that). Nope, not working. After dozen of tries seemed it will work, and then I realize my head is full of petrol from above. Went to fuel pump to investigate, one of connector pipes was broken (red things on pump picture). So, after dozen of tries I managed to improvise something and changed hose from plastic to rubber and found some old filter which seemed fine (new filter was leaking cause I didnt't torque it properly, stripped it). I used different style filter this time. So, I got it to work, leaking wise, but engine is working differently.
Maybe hose is bigger, maybe there is no enough pressure, who knows.
