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
• Porsche 928S4 5.0L 1987-92
• Porsche 928GT 5.0L 1989-91
• Porsche 928GTS 5.4L 1992-95

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.
