I have two vacuum lines on my new Chinese scooter that it is suggested should be replaced with American vacuum tubing.I have replaced most of theother lines except two that are in a difficult place to reach. One line goes from under the gas tank to the curved rubber tubing that is located in front of the carb. The line under the gas tank is the problem. The other line is located near the bottom of the motor on the left side and again in a place that is impossible to reach . Removing it is no problem but installing a new line would be very difficult.That line however is not connected to anything at the top end and sits along the side of the scoot frame My thought was to cut the vac line near the top connection under the gas tank and insert a small piece of metal tubing in it and attaching new line to that tube. I am concerned that this might restrict the air in the tubing too much.That tubing is 1/4 " in diameter .I would use the same procedure on the other line also. Any suggestions would be appreciated. crawdad

There should be a line from the front of gas tank to either the fuel pump or fuel filter, there is another line from the other side of gas, it should be going to the vapor canister, the one going from the engine is the vent hose, it should be hook up to the air box.

Thanks for the reply . I have the gas line going to the filter then to the carb. I also have a black vac line running from BEHIND the gas line connection and running to the curved rubber ( large hose piece ) that i in front of the carb. .The problem I have with this line is the hookup at the gas tank. It is under the tank and behind the gas line connection .You can see it but the space is so confined that trying yo put a new line in that space ,in not possible without lifting the gas tank up to make a new connection . Now the vac line on the left side as I said is not connected at the top end and is just lying against the frame. I see no place for it to be connected to .I thought it might be a drain for the carb.but it is near the bottom of the motor. Not near the carb. crawdad
