hello
1.For the pressure line I have a 124mm tube. In any case having a longer tube will give you an easier carburation (a more stable air pressure).
2.A 95mm tube on the fuel line.
When you cut the tubes you just have to think about the engine.
Longer tubes mean that the engine has to push a lot to make air/fuel flow. The best is to have the shortest fuel/pressure lines possible.
Just pay attention not to shorten the pressure tube too much because it can cause you some instability in the carburation
