E7ta-9k044-aa - please explain +
It has two pairs of tubes running in and out. Which for what? I think bigger diameter tubes are for fuel pump line, and smaller diameter are for return. Is this correct? Thould these two lines blow through equaly or one of them should have bigger resistance?

Are you referring to the fuel filter assembly underneath the driver's side in the frame rail?? Or the high-pressure in-line fuel pump that is closer to the front of the vehicle in the same general location? Or the in-tank unit? Or is it on the engine / fuel rail itself??

sorry 
I mean the thing between tank unit and main pump on the frame. It' s a container of black plastic, two lines in, two lines out. It's on the frame, same side that the filter and the pump are located but closer to rear of the vehicle. maybe under rear passanger's feet or even his butt.
Do you know if it can be disassembled and cleaned? I'm 200% sure i can not get one of these in Russia...

I'm guessing (after looking at autozone.com repair guide) that there were two different in-line low-pressure filter setups. Mine has the same canister assembly you're referring to, to the rear of the hi-pressure fuel pump I've never removed it, per se, other than to unbolt it from the frame to remove the fuel filter cartridge inside and clean out the bowl and replace the filter. Do you have another in-line filter that looks like this: http://www.autozone.com/images/cds/g...3d800b8658.gif ?? I am going to look under mine again sometime to see if I have two filters besides the in-tank filter. This is the first time I recall there being two different types of in-line filters.

I sure have this. I changed this yesterday. Used FRAM G3802A. Did not get better As for the "black thing" from the rear - I removed it. It looks like it can be disassembled. At least there are some ribs around the bowl perimeter (something you have to grab to when unscrewing) but it does not go. I aplied all my strength to it while the base was fixed securely, but did not go. Guess I'l have to throw it away and put jumper tubes in the line instead of it...

You need to leave the assembly bolted to the frame and use a strap wrench to break the cap loose. once it's loose, then you can unbolt the assembly from the frame and then finish removing the cap that holds the filter cartridge. Again, this is the first I've ever seen where both types of filters were installed. Supposedly, according to the repair guide on autozone.com, the "reservoir-type" filter (said assembly) should not require any maintenance -- I'm guessing because of this other in-line filter which you've replaced. The filter assembly, as well as the in-tank sock filter may also need replacement, if you feel they are affecting the operation of your truck. Hope this helps!

Probably because many of them do not even have a filter in them. I have unscrewed ones with only that single filter cannister and found nothing, right from the factory.
FWIW: I found taking it off the truck, putting it in a vise, and using water pump plyers and a rag to protect the cannister is the only way to get some of them unscrewed.

Found out mine was leaking today. Does anybody know the part number for the reservoir assembly? I need the round rubber gasket, kinda like a oil filter oring gasket but a larger one.

You can find just the fuel reservoir o-ring at https://www.amazon.com/M2-5x83-Buna-.../dp/B00NQWL8K0 in a 10-pack. It's .0359" thicker than the stock o-ring. I replaced mine and it's seals good, better than the stock one.
