Hose Line For Washer Jet.

The Hose Line for Washer Jet is a washer system plumbing component designed for the front windscreen washer system on Porsche 971.1 / 971.2 Panamera models.
This hose delivers washer fluid from the reservoir and washer pump to the washer jets/nozzles, ensuring the spray of fluid onto the front windscreen when the washer function is activated. It is an essential part of the fluid delivery path within the front washer system.
The hose line is engineered to remain flexible and reliable through heat, cold, and exposure to washer fluid chemicals. It ensures correct fluid flow, prevents leaks, and helps maintain the washer system’s performance and longevity.

What This Product Does:

• Carries washer fluid from the washer pump to the front windscreen washer jets
  
• Provides a sealed, kink-free path for fluid flow
  
• Works with the washer pump, reservoir, and other lines to deliver consistent spray volume and pressure
• Helps maintain clear visibility when cleaning the windscreen
  
  

Symptoms Of Hose Line Failure:

• No spray from front windscreen washer jets
• Weak or intermittent fluid flow — only drips or mist rather than a strong spray
  
• Washer fluid leaking inside the engine bay or under the vehicle
  
• Fluid loss — reservoir empties quickly without visible jet spray
  
• Hose shows visible damage — cracks, brittleness, soft spots, or flattened sections
  
• Washer pump runs normally, but no fluid dispenses

Why Replacement Matters:

• A fully functioning washer system helps maintain a clean windscreen — especially in rain, dust, mud, insect debris, or road film conditions — which is critical for safe driving.
• Leaks or blockages can cause the washer pump to run dry or at unfavorable pressure, leading to premature pump wear or failure, which is more expensive to repair.
  
• Having all washer components in proper working order reflects good maintenance and supports overall vehicle condition and value.
