Replacing a Mikuni Carburetor with a Weber Carburetor

[geezer101]

Holy crap - $220+ for a fuel pump!?!! I bet they'd be good for that price though...

I'm a bit perplexed as to where the last few parts of the carburetor kit go. These are the parts in question:


The 8mm aluminium barb as per the instructions is ment to block the water choke hose. Although as suggested by geezer, I replaced it with a straight fitting that I machined out of aluminium, thus eliminating the need for the 8mm aluminium barb. Seeing as the weber instructions that came with the carburetor kit didn't have pictures, I am questioning if this is the water choke they are referring to in the instructions:
