FUEL OVER FLOW TO THE ROAD / GROUND
FLOAT BOWL MINI HOSES = FUEL DRAINÂ (To do this before removing carbs)
It dangles down to the road.See this link on how to drain fuel before removing carbs
[Tutorial] How to swap Carb Main Jets – Hyosung GV & GT 125/250
Last picture…. FUEL PUMP yes correct 🙂“GREY PORT” = Vacuum input from intake rubber pipes.
“GOLD PORTS” ====> They have an arrow marked for fuel direction as you can see in the imageNow , please look at this tutorial below to help route the “fuel” pipes (gold ports only)
Please ignore the fact it is GTR 1255cc , it uses the same pump as a GV250 carby , Korea just moved the pump to another location
When the engine is cranking , make sure the fuel tap from your tank is switched on , and within 5 seconds (max or else starter motor overheats & more wear in the crank)
You will see the fuel shoot out of the pump in to a bucket when you point the hose down to it  (the same hose that is meant to send fuel to the carb itself)Hope this helps ?
