Fuel Line Help
 

Can anyone tell me the inside diameter on all the fuel lines on a 1992 G-9 Yamaha.
I have replaced the pump, Carburetor, Fuel filter, spark plug, air filter, fan shroud, battery and it still doesn't like to take off after you stop when riding it . It seems like after you ride it a while and stop it wont take off. So you let it sit for 10 minutes and it is fine. I am stumped and don't know what else to do. Also how do you check and see if it is pulling enough vacuum to run the fuel pump?

Do you know for sure that it has spark when it wont start? Need to carry a dynamic spark tester with you, and when it stops, test it for spark.

My G8 needed about 3 feet of each; 5/16" and 1/4". but your G9 may be a bit different.
