Hi. Trying to swap some carbs over onto my hurricane. The original carbs are vG20A but seized solid (bought bike as spares or repairs). The new carbs I have bought are vg26ab. Does anyone know where the 3 fuel lines go to? Obviously have the fuel in main line but there are 2 separate fuel lines off carbs 1 and 2, and 3 and 4 respectively. If anyone could help with where these 2 lines feed to I would be very appreciative. believe I am missing part 27 in diagram. Diagram does not show where main fuel line which runs to front of carbs feeds to.

Diagram of carbs. Missing Tee piece of number 27. There is a big fat fuel tube off number 5. Does this feed to main fuel pump and tubes 30 and 32 feed in?
