So, I have a Schwinn Graduate, 4 Stroke 50cc scooter, parents are going over the road trucking, so they are giving it to me, the only thing that needs to be fixed, is hooking the fuel lines where they go properly! I know this would be a cheap fix at a scooter store but I am BROKE and I very much need this scooter for work hopefully by tomorrow night. So basically, I used this scooter for a month, one day I was riding it, boom back tire locked up while driving, Dad took it away(He thought I broke it, turns out belt was just old and snapped) so it has a brand new belt. So he sells it to some kid, kid doesn't pay up, so they repo it, and turns out the kid had taken off the fuel lines, and not hooked them back up(for whatever reason that was). I have, no idea.. Where these dang lines go. And have so far only wasted time and I don't want to put gas into it till I know everything is plugged in correctly. If ANYONE has ANY kind of manual that SHOWS where the fuel lines go, that is all I need. I have been searching for 3 hours online for a dang manual that just shows exactly where the fuel lines need to go. I know this seems simple, but I know nothing of scooters. This is my last resort. So if anyone, please, has any pictures that just shows me where to put the dang plugs, it would be EXTREMELY appreciated. I just don't wanna mess this up taking random guesses. Thank you very much for reading!

out of youre fuel petcock/pump, there should be either 2 or 3 outlets.
if the pump has 2 outlets, it will be screwed into the fuel tank itself. one outlet, coming from the edge of the pump should go to the carb, the outlet on the carb will be near the air filter side of the carb., the other outlet that is in the center of the pump hooks into your air intake going into the motor, this will be AFTER the carb.
if you have 3 outlets, the 3rd outlet will be ran to your fuel tank.
if you use common sense, you cant really screw it up. fuel needs to go from the gas tank, to the carb on the air filter side. the air intake elbow's outlet, the one AFTER the carb, gives slight suction to make the diaphram inside the pump work, and release fuel.

On the 50cc scoots there is a fuel petcock usually mounted on the bottom of the fuel tank but sometimes it's mounted on the frame. The valve opens to allow fuel flow only when there is vacuum from the engine running. The vacuum comes from the intake manifold and runs to the vacuum port on the petcock. The fuel line connects to the carburetor on the side. To test it suck on the vacuum line. Fuel should run out of the fuel line while you suck on the vacuum line and stop flowing when you stop. There should be an in-line fuel filter installed between the petcock and the carburetor on tank mounted units. If you have the frame mounted unit the filter should be between the tank and the petcock. Tank mounted petcock: Frame mounted: Intake manifold showing where the vacuum line attaches: Fuel inlet on carburetor: This shows the vent on the carburetor that MUST be left open to the atmosphere. Do not connect anything to the vent! The tube on the bottom of the pic is the carb drain tube. It just dangles out the bottom. The screw next to it opens the drain. This shows how to adjust the carb: www.scooterforumonline.com/index.php/topic,1603.msg7405.html#msg7405
