Porsche 928 Washer Filler Neck to Reservoir Hose Kit – Cost-Effective Replacement

Over time, the original hose running from the washer filler neck to the windshield washer reservoir on the Porsche 928 becomes brittle, cracked or torn. Exposure to heat, age and washer fluid chemicals causes deterioration, leading to leaks and inefficient washer system operation.

Fits:

  • Porsche 928 4.5L 1978-82
  • Porsche 928S 4.7L 1981-83
  • Porsche 928S2 4.7L 1984-86
  • Porsche 928S4 5.0L 1987-92
  • Porsche 928GT 5.0L 1989-91
  • Porsche 928GTS 5.4L 1992-95

What This Hose Kit Does

This hose connects the washer filler neck to the windshield washer reservoir, allowing fluid to flow properly into the tank during filling.

A damaged or perished hose can cause:

• Washer fluid leaks inside the wing area
• Slow or incomplete filling of the reservoir
• Fluid loss before reaching the tank
• Unpleasant odours from trapped washer fluid

Replacing the hose restores correct washer system function and prevents fluid loss.
