Ageing Porsche 928 washer systems commonly suffer from cracked filler necks, brittle caps and torn connecting hoses. These failures can cause washer fluid leaks, difficulty filling the reservoir and unwanted fluid loss inside the wing area.

This kit replaces all key components in one package, ensuring reliable and leak-free operation.

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

Diagram Ref No 32

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.

Fits All Left Hand Drive Porsche 928 Models
Designed to fit every LHD Porsche 928 from 1977 to 1995, including early production cars.

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

Features
• Completely redesigned using 3D CAD
• High-strength construction
• No rust-prone metal ring
• White finish for factory-correct look
• Suitable for all Porsche 928 models (1977–1995)

Ideal For:
• Porsche 928 washer system restoration
• Replacing cracked or brittle filler necks
• Preventative maintenance on classic 928 models
• Engine bay refurbishment projects
• Solving washer fluid leak issues

Windscreen Washer Bottle Hose 

The windscreen washer bottle hose is a direct replacement hose designed to connect the washer filler neck to the washer reservoir on the Porsche 928.

Over time, original washer hoses become brittle, crack, or split due to age, heat exposure and constant contact with washer fluid. A deteriorated hose can lead to leaks, slow filling, or washer fluid escaping before reaching the reservoir.

  • 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

Diagram Ref No 12

This replacement hose restores proper washer system function and ensures clean, efficient fluid transfer from the filler neck to the washer bottle.

What This Washer Hose Does

The hose forms a critical link in the windscreen washer system. It:
• Transfers washer fluid from the filler neck to the reservoir

• Maintains proper washer bottle filling
• Supports reliable windscreen cleaning performance

A damaged hose can cause fluid loss, poor washer performance and unnecessary mess within the vehicle bodywork area.

Why Replace Your PCG18128650 Washer Hose?

About Washer pumps / bottles / jets

Washer Pumps, Washer Bottles & Washer Jets – Clear Vision for Every Drive

Washer pumps, bottles, and jets are key components of your Porsche’s windscreen cleaning system. They work together to deliver washer fluid from the reservoir through the pump and jets, keeping your windscreen clear of dirt, bugs, and debris for safe driving visibility in all conditions.

At Design911, we supply a comprehensive range of genuine and high-quality washer system components - including washer bottles (reservoirs), electric washer pumps, and precision spray jets — for all Porsche models such as the 911, Boxster, Cayman, Cayenne, Macan, and Panamera. Every part is designed to offer high levels of fitment and performance for dependable cleaning power and long-term reliability.

What Do Washer Pumps, Bottles and Jets Do?

  • Washer Bottle / Reservoir: Stores the washer fluid and is typically located in the engine bay or boot area.
  • Washer Pump: An electric motor that pressurises the fluid and pushes it through the lines toward the 
  • Washer Jets / Nozzles: Deliver a fine, even spray of fluid onto the windscreen or headlights for effective cleaning coverage.

Together, these components ensure your windscreen remains clean and streak-free, maintaining visibility and safety in all weather conditions.

Why Do Washer Components Fail?
Over time, washer system parts can degrade or fail due to wear, contamination, or environmental exposure. Common causes include:

  • Pump failure due to internal corrosion or debris blocking the impeller.
  • Leaking washer bottles from cracks, freezing, or age-related wear.
  • Clogged jets caused by limescale, dirt, or poor-quality washer fluid.
  • Electrical issues such as damaged wiring or corroded connectors.
  • Perished hoses or seals leading to fluid leaks and reduced pressure.

Symptoms of failure include weak or no spray from the jets, fluid leaks, or a pump that doesn’t activate when the washer stalk is used.

Why Replace Faulty Washer Components?

A properly functioning washer system is essential for visibility and road safety. Replacing worn or damaged components ensures your windscreen remains clean and clear in all driving conditions.

Benefits of replacement include:

  • Restored washer performance and pressure.
  • Improved visibility and safety in rain or road spray.
  • Prevention of leaks and electrical damage.
  • High-quality parts for perfect fitment and durability.
