What are the ID size of my fuel and air hoses in my scooter listed in my sig? I am ordering me blue air lines and red fuel lines and I forgot what they are. Thanks!

1/4 for the Fuel Lines and 3/16 for the Vacuum lines.

I had a 50 foot tall electric scrolling sign erected over the massive entranceway to Scooter Doc headquarters that reads: Most of the time on a 150cc GY6 scooter you'll have 1/4" nipple on the gas tank but the inlet to the carb is 3/16". If you have a vacuum fuel valve they're usually 1/4" on the tank side and 3/16" on the outlet. So just use 1/4" fuel line up to the valve by putting a 1/4" fuel filter in before the vac valve and then 3/16" from vac valve to carb. You can use 3/16" fuel line for the vac lines but you can get line specifically made for vacuum purposes. However, I'd measure before you order because....well...you know. Rich

My Lifan are 3/16" for all lines stock. I use Tygon ( F4040-A) 3/16ID by 5/16 OD
Then wrap all connections with 5 or 6 inch nylon zip ties and pull tight with pliers
