had a hose come off my emissions recovery system By bobthetechguy (Read 9,000 times)

Look on the INTAKE MANIFOLD and see if there is a CONNECTOR with nothing on it if so connect it there. Otherwise look at the VACUUM HOSES coming off the INTAKE MANIFOLD and follow the VACUUM HOSE or HOSES and you will most likly see a "T" connector or a "T" connector with one end open then connect it to that.

Here is a INTAKE MANIFOLD if you do not know what it is: See the nipples coming off of it that is for VACUUM HOSES. If any VACUUM PORT is LEFT open it will bog and cause all kinds of problems.

I don't know if it would help or not, but I subscribe to cycleteacher.com for $5/month. I had a question about vacuum lines a few days ago and they made a video for me, available to all their subscribers, which details the vac/fuel configuration on a 150 GY6.

Doc, I'm beginning to think we might need that service of yours......

I found it, I found it....the diagram that explains all of this!!:

There it is, the hose comes off of the PAIR canister and runs to the intake manifold, or as we say in the scooter forum biz....vacuum source. Many hoses can attach to the vacuum source. The petcock hose, the air cut valve hose, the vapor canister hose. I really like saying hose, I don't mind saying petcock either. Look 'em up, they're in the dictionary.

Mine doesnt have a connector on that side of the intake. Perhaps at one time the intake was replaced from a scooter that didnt have PAIR?

[bobthetechguy]

Thanks for the picture. Thats perfectly what i was looking for

If your intake manifold has only one Vacuum line connector then you should have a "T" or a "Y" connector, follow that single Vacuum hose coming off the intake manifold. If not then you will NEED to get a "T" or a "Y" connector so that you can attach that hose to it.

Yes exactly, Alley was spot on. It doesn't matter, and I went through it when I first got into scooters. You can have a vacuum nipple on one side of the intake manifold, or both sides and it does NOT matter. It is the same vacuum source even if you just have the nipple on one side and split it with a T, or both sides. It is still the vacuum source. Theoretically you could keep splitting vacuum sources, but just like electrical current, it would eventually start to be diluted. Molecules are molecules, electrons are electrons, they are both a finite resource.
