I have a 2008 bike and have pretty much everything put back together but have no clue what to do when it comes to my fuel and vac lines. I saw other posts for similar bikes that helped but haven’t found anything for my bike. I am a first-time bike owner so dumbing it down is appreciated. I’ll drop pictures in to help explain my predicament better.
I do have the top lines coming off the top of the carb hooked up and just running to the ground (not colored)
Anything in yellow I’m completely lost on…
Anything colored (i.e. red, green, blue) I THINK (emphasis on think) I have correctly hooked up.

Hey can you attach the pictures on here ? Just click “Add Media” on this reply box below this forum topic.
The google drive link says access denied anyway.
The fuel setup is the same from GT to GV but GV has the luxury having less vacuum pipes because it uses a manual tap.
If you have a “fake emissions ball” (aka EGR) (aka AIS Valve) , you can bypass it and block the port connecting the engine , block the extra pipe from the manifold rubber feeding it, block the extra hole under the airbox.
Now doing the fuel setup for your GV should be a breeze with new lines.

Sorry about that! I have the pictures here…
I think I started to catch on to what you were saying but am not 100% sure what to do still.

#3 = FUEL OVERFLOW DRAIN PIPE (MUST GO TO THE ROAD)
BLUE = Tap to fuel filter.
BLUE = CORRECT. => TANK .
RED = TO CARB = CORRECT .
#4 = VACUUM => TO RUBBER INTAKE MANIFOLD .
GREEN = BLOCK IT. (BYPASS) (FAKE EMISSIONS)DELETE FAKE EMISSIONS VALVE FROM BIKE AND BLOCK THE PIPES TIGHT.
YOU DON’T NEED IT.YELLOW = CARB FUEL DRAIN (Maintanance only)

SEE COMMENTS ABOVE ^ = DELETE FAKE EMISSIONS VALVE AND BLOCK PIPES
(LESS STRESS FOR YOU 😉 )
