Vacuum Hose Connectors
To disconnect vacuum hoses, pull on the end, not the middle of the hose.
When using a vacuum gauge, never force the hose onto a connector that is too large. Use a step-down adapter instead.
Once the hose has been stretched, it may leak.
Tag hoses before disconnecting them:
When disconnecting vacuum hoses, use tags to identify how they should be reconnected.
After completing a job, double check that the vacuum hoses are properly connected.
A label under the hood shows the proper layout.
