## ⚠️ Common Signs of Failure

-   Line hardened, cracked or split at the end where it pushes onto its stub
-   Line pulled off or blown off its connection
-   Rough idle, poor running or a hiss that changes with engine speed
-   Soft, collapsed section that closes under vacuum
-   Line chafed flat where it crosses a bracket or another component

## 🛠️ Service Notes

-   Renew the line rather than trimming back and re-pushing a cracked end, as a shortened line is then pulled tight on its route and splits again
