Just found out that my gaz lines( both to the engine and return) next to the clutch and under the backseats are rusted. And smells octane.Probably leaking.
I have seen my garagiste do it once but making sure about it.

2 questions.
1 Are they under pressure? That prevents me to cut them?
2 can i just replace with rubber tubes? And what kind should i get?

 

yeah use rubber tube and let us know when u die there is not pressure to the line but gas will spray when u cut it your best bet is to let a shop do it
