The windscreen washer jet plays a simple but essential role in the washer system by directing washer fluid evenly onto the windscreen. This allows the wiper blades to effectively remove dirt, dust, insects and road grime, ensuring clear visibility in all driving conditions. The tall chrome design also contributes to the authentic period appearance of the front bonnet, making it an important finishing detail during any restoration.

Manufactured to OE Match standards, this replacement washer jet offers the correct fit, finish and chrome appearance, making it ideal for concours restorations, routine maintenance or replacing worn original components.

Why Do Windscreen Washer Jets Fail?

Over many years of use, washer jets are continually exposed to weather, road dirt, UV light and hard water deposits. These conditions can cause the small nozzle opening to become blocked, reducing or completely preventing washer fluid from reaching the windscreen.

The external chrome finish may also become pitted, corroded or damaged through age and exposure to the elements, detracting from the appearance of the vehicle. In some cases, accidental damage during polishing or bonnet work can bend the nozzle, affecting the spray pattern and reducing cleaning effectiveness.

As the original washer jets on many Porsche 356 models are now over sixty years old, deterioration is common even on well-maintained vehicles.

When Should They Be Replaced?

Replacement is recommended whenever the washer jet no longer produces a consistent spray pattern or shows visible signs of deterioration.

Common signs include:

• Weak or uneven washer spray
• Blocked or partially blocked nozzle
• Corroded or pitted chrome finish
• Bent or damaged nozzle
• Washer fluid missing the windscreen
• During concours restorations or bonnet refurbishment

Replacing tired washer jets restores both the functionality of the washer system and the authentic appearance of the vehicle.

Key Features

• Correct tall chrome design
• Restores effective washer fluid spray pattern
• Improves driver visibility in poor weather
• High-quality chrome finish
• Precision manufactured for accurate fit
• Ideal for restoration and routine maintenance

Washer Tank Kit, With Cover Socket & Hose.
Restore reliable windscreen washer operation with this OE Match Washer Tank Kit, supplied complete with cover, socket and hose. Designed for compatible classic vehicle applications, the washer tank provides the reservoir required to store and supply washer fluid for cleaning the windscreen.

Fits:
Porsche 356B T6 - 1962 to 1963
Porsche 356C - 1963 to 1965

Brand new OEM quality washer tank with the cover lid the 90 degree socket elbow, the bottom screen, and we have included a 10 1/2" hose with it that will cover up to the first connection to the jet. This is a complete kit! to replace that cracked worn out washer reservoir tank and get a new one today.
The screen on the bottom of the cap has the original metal valve to help with the suction. This is to avoid burning out the wiper motor.

The windscreen washer system plays an important role in maintaining clear visibility by delivering cleaning fluid to the windscreen, where it works with the wipers to remove road dirt, dust, insects, salt and other contamination. The reservoir must securely contain the washer fluid and provide a dependable connection to the rest of the washer system.  

What This Product Does:

• Stores the fluid used by the windscreen washer system.
• Supplies washer fluid for windscreen cleaning.
• Helps maintain a readily available supply of cleaning fluid.
• Works with the vehicle's washer system to support clear forward visibility.
• Includes the washer tank, cover, socket and hose.
• Replaces multiple worn or missing washer-system components together.
• Helps prevent fluid loss caused by a cracked or damaged reservoir.
• Provides secure connections when correctly installed.
• Supports consistent and reliable washer operation.
• Provides an OE-style solution suitable for classic vehicle restoration.

Symptoms Of Wear Or Failure:

• Washer fluid leaking from the reservoir.
• The washer fluid level dropping without frequent use.
• Visible cracks, splits or deterioration in the tank.
• Fluid leaking around fittings or hose connections.
• Brittle, cracked, hardened or damaged washer hoses.
• Loose or damaged connections.
• A damaged or missing reservoir cover.
• Washer fluid collecting underneath or around the tank.
• Weak or inconsistent washer fluid delivery.
• Difficulty keeping the washer reservoir filled.
• Washer fluid failing to reach the windscreen.
• Age-related deterioration discovered during vehicle restoration.

Why Replacement Matters:

• A cracked or leaking washer reservoir can allow the cleaning fluid to escape, leaving little or no fluid available when the windscreen needs cleaning. This may become particularly problematic during wet or dirty driving conditions when road spray can quickly reduce visibility.
• Clear forward visibility is essential for safe vehicle operation. The windscreen washer system complements the wipers by helping loosen and remove contamination that cannot be effectively cleared by the wiper blades alone.
• Ageing hoses, fittings and related components can also compromise washer operation. A hardened or split hose may leak fluid before it reaches the windscreen, while damaged connections can cause intermittent or complete loss of washer function.
• Replacing the tank together with associated components can be particularly beneficial during a classic vehicle restoration. It reduces reliance on aged parts and helps provide a cleaner, more complete and original-style installation.
• Replacing worn, damaged or missing components with this OE Match Washer Tank Kit with Cover, Socket & Hose helps restore dependable washer fluid storage and delivery, supporting effective windscreen cleaning and a well-finished restoration.

• Position on Vehicle: Mounted at the top of the washer fluid reservoir (windshield washer tank) in the front compartment or accessory bay; includes the attached hose for correct routing and connection.

• Applications: Ideal for use when the original cap is cracked, missing, leaking washer fluid, or when restoring the original appearance and function of the windshield washer system on a classic Porsche.

A properly functioning washer system cap ensures the washer fluid tank remains sealed, preventing contamination or evaporation and allowing the system to maintain correct pressure and fluid delivery when you need to clean your windshield. A cracked or missing cap can allow debris or moisture into the system, cause fluid leakage, or reduce washer effectiveness - critical during poor weather conditions or for safe driving. Replacing cap restores function, prevents failures and preserves the original system integrity.

When and why to replace:
• Washer fluid leaks from the reservoir cap or hose connection.
• Cap shows visible cracks, warping, or the hose connection is loose or detached.
• During restoration or servicing of the washer system when the original cap is removed.
• If the washer tank or hose has been replaced and original cap is missing or the seal has aged.
• For collectors looking to maintain correct original component appearance and function.
