      Are you able to post pictures of how far you have come ? and the tank tap too. = Just so we see the situation,    I or someone might try to draw a diagram out of it for you.

      Welcome to the forum!

      Confirm with your bike with this user-submitted document which matches our carbs.

      Okay so I got the blue hose which I presume is the fuel intake from tank to fuel pump the greens running from pump to the carb I do believe and then where orange is I have the hose but not really sure honestly

       

       

      Now this is the underside of the fuel tank you got the two which are obviously fuel lines I just don’t know which goes to which and then as for the red that actually seemed to be a place for a third hose???? My friend thought that it had a stopper or cover or something that it was missing so he make shift made one but honestly I haven’t a clue and don’t plan on trying to start it until I do.

      G’day Hannah pool. Under Tank connections:

      PINK is a 6mm Fuel Line on my GT250R. Fuel runs OUT from the tanks petcock there & connects to the FUEL-FILTER & then connects to the VACCUM PUMP.

      Note: Vacuum PUMP has an ARROW-IN, an ARROW-OUT & a LETTER P stamped on the front of the pump . The arrows are located where the fuel lines connect to it.

      Arrow-IN is FUEL-INTO-PUMP (from Fuel-Filter & Tank)
      Arrow-OUT is FUEL-INTO-CARBURETOR
      Letter-P is for VACCUM HOSE (from INTAKE MANIFOLD at CYLINDER-1 or FRONT CYLINDER)
      LIGHT BLUE is 5mm hose like all the VACUUM LINES.
      RED is idk. Looks like a home-made drain-plug but i don’t know the GV650’s.
      I’d glue that screw with a bit of selleys all clear, so it doesn’t vibrate out, then fix it more seriously after a few rides.
      I’d also start the bike up, if all the FLUIDS are ok. arm it up, get it lubed, stop if you hear any funny noises or leaks.
      Keep some water nearby when you start it up – if it leaks fuel onto a hot exhaust it may ignite but i doubt it. Will probably just evaporate.
      Flick the OFF SWITCH or turn the KEY OFF & pour water or sand on the fire. Fire Extinguishers also work.
      It won’t catch on fire but it can’t hurt to have water in a bucket nearby to wash-off drips.

      6mm Fuel Lines & 5mm Vacuum Hoses on my Hyosung GT250R.

      Your 650 hoses will be bigger than this. It matters not.

      The big hoses are for fuel & the smaller ones are vacuum.

      I think the ORANGE BOX in your top photo is for VACUUM HOSE & connects to your Pump.
