Installing an Airbox

oniondip · 10-09-2014, 06:38 PM

I need to install the snorkel type airbox back into my 150cc scooter but I don't know the vacuum line diagram. There are 2 vacuum lines on the box and I'm not sure where they go. Is one and input and one and output? I have a dual intake manifold.

Thanks

There are no vacuum lines that go to the air filter. The lines you are talking about have to do with recycling crankcase breather gases, and fumes escaping through your fuel tank vent tube. If you have removed the hardware parts of your emissions system (as a lot of us have), just cap off the open nipples on the air box. Any auto parts store will sell vac caps in an assortment pack....30 pieces of assorted sizes..
