Porsche 928 Windscreen Washer Reservoir Filler Neck – Redesigned High-Strength Replacement
The Porsche 928 washer filler neck is a known weak point on ageing vehicles. Over time, the original part becomes brittle, cracks during removal, or suffers corrosion due to its internal metal ring.
We have completely redesigned this windscreen washer
reservoir filler neck using modern 3D modelling technology to create a
stronger, more durable and corrosion-resistant replacement suitable for all
Porsche 928 model years — including early 1977 cars.
Fits:
- Porsche 928 4.5L 1978-82
- Porsche 928S 4.7L 1981-83
- Porsche 928S2 4.7L 1984-86

What This Filler Neck Does
The filler neck connects the washer bottle to the upper fill point, allowing washer fluid to be poured safely into the reservoir.
A damaged or cracked filler neck can cause:
• Washer fluid leaks inside the wing
• Difficulty filling the washer reservoir
• Fluid spillage during refilling
• Deterioration of surrounding bodywork
Replacing the filler neck restores correct washer system operation and prevents unnecessary leaks.
Why Upgrade to Our Redesigned Porsche 928 Washer Filler Neck?
Stronger Than the Original
Our redesigned version eliminates the structural weaknesses of the factory
part. It is engineered for improved durability and long-term reliability.
No Internal Metal Ring
Unlike the original design, this filler neck does not use a metal reinforcement
ring that can rust over time. This prevents corrosion-related failure.
Maintains Original Appearance
Now produced in white with a smooth surface finish to closely match the factory
look. This ensures a clean and authentic engine bay appearance.

Designed to fit every LHD Porsche 928 from 1977 to 1995, including early production

Compatible With Original Cap
The genuine Porsche cover cap fits directly onto this filler neck, maintaining
OEM functionality and appearance.
