Need a part number
The canister I ended up getting was a 211-470-01-59, which I think is for a newer model W211 with a different connector than the one my 2004 has for the hose to the fuel filler neck assembly. Is that connector and hose have a part number that I can order without buying an entire filler neck assembly? The adapter that I cobbled together from the old canister and some hoses/clamps just isn't a permanent fix and I keep getting the red warning that my fuel cap isn't on when it is on. The pics below show a generic filler neck with the hose/connector circled in red. The other pic shows the old and new canisters with the new canister connection point in the red square.

I need some help in searching the part number as im not good to understand these pics with part numbers.
From fuel neck, I know about two pipes going to petrol tank, black one is for fuel and white plastic pipe which mechanic calls as air return pipe.
So basically, as per my mechanic, fuel goes in using black pipe and air comes out from white pipe it doesn't cause airlock.
That white pipe got broken and so when I was filling the tank to full, petrol was leaking from this white pipe. Mechanic just removed cracked piece and fixed a stopper to end of white pipe (which is coming from tank side) so petrol wont come out.
Now, whenever I am filling the fuel, it trips after every 2, 3 liters. I have to start fueling again. I need to replace that white plastic pipe which broke down.
I went to spareparts shops here and they were all selling me complete fuel neck, not a single pipe. Which is very expensive and im very tight on my pockets now a days.
I understood from articles and pictures, that individual parts can be purchased and afixed, but I dont know which part or parts should I order.
Any help in this regard is appreciated !
Here is the VIN number: WDBUF52X59B430579
