go to an auto parts store, and but ??ft piece of rubber fuel line. I dont know for sure, but if bandit has vac petcock, you will need to set it on 'pri' . or run a second line to the petcock.
Remove tank, place it above carbs and hook it up.
Run the bike for a minute or so to get all the air out of the line.
when done shut off the petcock and remove hose from tank, holding it up while bike is running to get most of the fuel out of the line....
