FLOAT BOWL MINI HOSES = FUEL DRAIN  (To do this before removing carbs)
It dangles down to the road.

See this link on how to drain fuel before removing carbs

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 image

Now , 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 ?
