Taotao ATM150-A Evo scooter - replacement of fuel and vacuum lines 

The fuel line from the very bottom of the carb has a "spring" around it and is just a drain hose for the float bowl. It leads down to the belt housing and has a screw that you can loosen to drain the carb's float bowl. There is a vacuum line that leads from the intake manifold to the "petcock". This signals that the carb needs fuel and opens the diaphragm to allow fuel to flow to the carb. If this is not connected or has a hole in it, the engine will not run. There is another "vacuum" line that runs to the air cleaner housing which doesn't do anything but recycle unburned gas fumes. It is not necessary to run the engine.

Thanks

also the line coming out of the air box tube , does that go directly to the cvt case? also do i need that

Never seen an electric fuel pump on the scooters I’ve owned but there’s multiple ways to check if the fuel is getting to the carb. Key on, undo the fuel line before the fuel filter and see if gas pours out, or with electric fuel pumps you can listen 👂 with your ear close to the gas tank for a whirring sound, it’s brief but you’ll know when you hear it

Raul Gonzalez it should matter what as long it's say you can use it for 59cc 150cc

You can find any parts you need for any of these on eBay.

The top of the head ? The thicker hose ? It is positive crank case ventilation (PCV) and Doesnt really matter as far as the engine running, mine is just hangin out down there when I drive my scooter but you can drill a hole in the air filter and insert the hose in there to recycle the pcv air

L

yes.

@@thersten why ?

@@shannonmcdonough8871 because I said so. And bc that vacuum isn't being used.

it could be capped off at the nipple.

Check block plate

i go to ebay.

you can have more than one filter. they just can't be plugged or too restricted.
