⚙️ Key Features

• Works with vacuum switch 20560843
• Supported by air-cleaner bracket hardware

🔌 Function

Carries the intake-pressure signal to the restriction switch so a clogged air filter can be detected.

⚠️ Common Signs of Failure

• Restriction warning does not operate
• Cracked or blocked tube
• Loose connection
• False restriction alarm
• Tube chafing

🛠️ Service Notes

• This line only carries the pressure signal to restriction switch 20560843 - it is not part of the main charge-air path, so a leak here reads as a false or missing filter-restriction warning rather than a loss of power
• It supersedes the earlier air tube 21955519 - if that older number is what the parts history shows for the engine, this is the current number to order
