I looked on Russian parts site - the fuel tank design has been changed many times.
I have an old parts book. On page 47/2, it shows a tank with no expansion tank. The vent goes straight from the top of tank to a canister in the engine bay, via an under car valve. On Page 47/4 it has a similar diagram, but with an expansion tank. But the early cars don't have those canisters, do they?
Then, on Page 47.1 11-700/5 of engine manual it again shows a tank without an expansion tank. It says later that models 107.02 and 116 have an expansion tank integrated into the actual tank. But then this isn't a 107.02 is it. But maybe someone changed the tank?
On page 706/1 it says that for the 107.043, starting Sept 1971 chassis 0003443, an expansion tank with 5 connections was fitted. Prior to that the expansion tank had 3 connections. This seems to say that even early cars did have an expansion tank, but one with 3 connections.
So depending on chassis number, you may need either a 3 or 5 connector expansion tank.
One more little mystery....

Man, I run into this s@%t all the time on this car. My fuel pump/filter set-up is a pre-1st generation set-up for the R107.
I played hell getting the pieces that would work...
My chassis is 107.043 #4542, so after the number that you mentioned, but it lists the build date as Dec 71 (not that probably correlates to a .043...). The tank has all the connections for the expansion tank: the 2 on the left are connected to each other in a loop, the one furthest to the right vents to behind the filler door & the one right next to it is capped off w/ a bolt in the hose. The one in the middle goes under the car to a line that runs to the charcoal canister under the hood. That last one was completely bodged & I think it was originally the one that just vented open under the car: for one: the hose was rubber 1/2 way & then hardware store steel line the rest of the way to the front of the car and 2: the line that goes under the car has one of those plastic nipples that MB only puts on drains & not on connections.
I can say that all the hoses/connectors on the tank are correct period MB bits & everywhere else on the car where things have been messed with it's rubber lines & 1/4" US hose clamps...
