Reply To: [How to Tutorial] Change / Upgrade fuel lines & fuel filter on CARBY GV125 GV250 Diagram
Yes when the bike cranks up (throttle closed) , you will see it go inside the fuel filter if its a clear fuel filter (not the cloudy ones that are hard to see)
Then , make sure the “pump” next to the battery tray is connected the right way as per tutorial on this thread.
When cranking the bike, see if the “hose” going to the carb shoots fuel out in to a bucket next, let us know how it comes out.
