Hey, I’m trying to identify all the hoses on the underside of the Tuono 1000R's fuel tank. The official manual shows four hoses (identified as 4, 5, 9, 10) but in reality, there's six.

There’s no documentation available that explains what these are or what they’re supposed to connect to. The previous owner blocked the overflow port when they removed the EVAP canister, and it ran fine that way, so I’m not too concerned. I’m thinking of grounding all of these, but first, I need to figure out why it’s dumping so much unburnt fuel. One step at a time though.​

No clue Danny, but the question is well presented. Hopefully someone knows.
 
Best ask the question over at AF1 forum. I am sure some one there could sort you out.
