If you check the stator and it's fine, I am still running stock fuel line on my Yerf 3206 GY6 just fine, but my brother has a Schwinn scooter with the GY6 150cc on it. It has an inline fuel pump that is ran off of a vacuum hose just below the fuel tank. I'm guessing that it is because the motor will be ran at higher RPMs for longer duration while on the highway?
Anyway, I think the scooter also comes stock with an 8 pole stator and I thought I read on Buggy Depot that the GY6 on the buggies has a 6 pole. Not really sure as I'm new to all this, but I made these observations in the last couple days.
If you wind up needing a fuel pump for it, all the engine parts from that scooter seem like they will work on my buggy. Same engine, different application.
Hope you can get it figured out.
