This valve can take the place of any fuel valve that is not connected to bottom of gas tank. There are alot of 150cc chinese scooters that use a frame mount round fuel valve so this can take its place with a high quality fuel valve used in motorcycles. Can mount this one in same place or mount somewhere it will get great flow from gravity.
Alot of problems with chinese scooters or any other is gas flow because of poor quality of parts and materials used in making the parts. This fuel valve or pump solves many problems. If your 150 is having mid range problems this could help or simply if your valve is not working at all get the best and stop worrying about it.
When installing new fuel pumps sometimes fuel line seems to small, very easy to fix and make your life much better.
Heat fuel or air line up with lighter and slide it right on connection and it will cool down and stay forever do not do it till you are ready it will not come back off.
