It has a number 7X0.201.920 embossed on it. Searching all I can find is a Brazilian site advertising a used one as " Reservatorio Canister Kombi 1.4 Flex" It has 3 thin pipes attached, two go to the fuel tank and the third goes nowhere.
Id say it’s the charcoal filter, because your bus has had an engine swap I’d say it’s no longer used, but originally I don’t think it would have had 2 lines to fuel tank ? I’d maybe do a bit more internet searching just to be sure !
It seems that in Brazil the term “Flex” refers to alcohol fuel. There is nothing inside it, it is hollow. It may have been connected to a charcoal filter which was not present but there were certainly two pipes going to the fuel tank.I have removed it and plugged the thin hoses from the tank.
