The fuel tank cap plays an essential role in sealing the fuel tank, helping to prevent fuel contamination while reducing the risk of fuel vapour escaping. Over time, original caps can suffer from corrosion, worn sealing surfaces, damaged threads and deteriorated finishes, particularly after decades of use and exposure to moisture, fuel and changing temperatures.
Manufactured to OE Match standards, this replacement cap combines dependable sealing performance with the correct period-correct yellow zinc finish, making it an ideal choice for concours restorations, sympathetic refurbishments and routine maintenance.
What Does the Fuel Tank Cap Do?
The fuel tank cap provides a secure seal for the fuel filler neck, protecting the fuel system from dirt, dust and moisture while helping maintain correct tank pressure.
Its primary functions include:
- Sealing the fuel tank.
- Helping prevent fuel leaks.
- Protecting against contamination.
- Reducing fuel vapour loss.
- Maintaining safe operation of the fuel system.
- Completing the original appearance of the fuel filler compartment.
A properly functioning fuel cap is an important component for both vehicle safety and reliable operation.
Why Replace the Fuel Tank Cap?
Years of regular use and environmental exposure can cause the fuel cap to deteriorate.
Common issues include:
- Corrosion of the original finish.
- Damaged or worn sealing surfaces.
- Worn locking tabs or threads.
- Fuel odours caused by poor sealing.
- Cosmetic deterioration during restoration.
- Missing or incorrect replacement caps.
Replacing the fuel cap restores both the appearance and functionality of the fuel system while helping maintain the originality of your classic Porsche.

- Porsche 356B 1959-63
- Porsche 356C 1963-65
This OE Match oil filler and breather is a replacement engine oil system component for Porsche 356B and 356C models. It is designed to match the original-style fitment and function, helping provide the correct oil filling point and crankcase breathing arrangement.
Fits:
Porsche 356B - 1959 to 1963
Porsche 356C - 1963 to 1965
Diagram ref no 14
The oil filler and breather assembly allows engine oil to be added to the engine while also supporting crankcase ventilation. It helps manage oil vapour and pressure within the engine, allowing the crankcase to breathe correctly as part of the engine lubrication and ventilation system.
Functions
• Replaces the oil filler and breather assembly
• Provides the engine oil filling point
• Supports crankcase ventilation and breathing
• Helps manage oil vapour and internal crankcase pressure
• Supports correct engine lubrication system operation
• Replaces damaged, corroded, blocked, leaking, or missing original assemblies
• OE Match replacement for Porsche 356B and 356C engine restoration.
Why Replace This Part?
Oil filler and breather assemblies can corrode, block, leak, become damaged, or go missing due to age, engine heat, oil vapour, moisture, and previous repairs. A faulty breather can contribute to oil leaks, poor crankcase ventilation, oil mist, pressure build-up, or an incomplete engine bay appearance. Replacing the assembly helps restore correct oil system function and original-style engine detail.
When to Replace This Part
• The oil filler or breather assembly is damaged, rusty, blocked, or missing
• Oil vapour, misting, or leakage is present around the breather area
• Crankcase ventilation is restricted or not working correctly
• The engine oil filler area is being restored
• The engine has been removed, rebuilt, or resealed
• Incorrect or non-original breather parts have been fitted
• The vehicle is undergoing Porsche 356B or 356C engine bay restoration.
Where it fits on the car
This oil filler and breather assembly fits on the engine oil filler / crankcase ventilation area on Porsche 356B and 356C models. It forms part of the engine lubrication and breathing system.

Manufactured from high-quality automotive-grade materials with an integrated oil-resistant sealing gasket, the cap is engineered to withstand continual exposure to engine oil, heat, vibration and harsh engine bay conditions. Precision-moulded to OE dimensions, it provides direct OE-style fitment and a positive locking action, making it the ideal replacement for worn, damaged or missing original oil tank caps.
What This Product Does:
- Seals the engine oil tank securely.
- Prevents engine oil leaks from the filler neck.
- Protects the lubrication system from dirt, dust and moisture.
- Helps maintain correct crankcase and oil system integrity.
- Provides a secure locking fit during vehicle operation.
- Supports reliable engine lubrication.
- Restores factory sealing performance.
- Forms an essential part of the engine lubrication system.
Symptoms Of Wear Or Failure:
- Engine oil leaking around the filler neck.
- Oil residue on or around the oil tank.
- Loose or poorly fitting oil cap.
- Cracked or damaged cap housing.
- Perished, flattened or missing sealing gasket.
- Oil smell from the engine bay.
- Dirt or moisture entering the oil tank.
- Difficulty securing the cap correctly.
- Visible wear or deterioration due to heat exposure.
- Engine bay contamination caused by oil seepage.
Why Replacement Matters:
- The oil tank cap is continually exposed to engine heat, oil vapours, vibration and repeated removal during servicing. Over time, the sealing gasket can harden or deteriorate, while the cap itself may crack, warp or lose its ability to lock securely.
- A faulty oil tank cap can allow oil to leak from the filler neck, creating engine bay contamination and increasing the risk of low oil levels. It can also permit dirt, moisture and other contaminants to enter the lubrication system, potentially accelerating engine wear and reducing long-term reliability.
- Replacing a worn or damaged oil tank cap restores a secure, leak-free seal and helps maintain the integrity of the engine lubrication system. The OE Match Oil Tank Cap is manufactured to OE standards using premium-quality materials, providing factory-style fitment, dependable sealing performance and long-lasting durability, ensuring the reliability and protection expected from your Porsche.

OEMatch filler neck parts for Porsche models provide the connection between the engine or oil reservoir and the filler cap, enabling controlled oil refilling while maintaining the lubrication system seal. This collection covers filler necks, caps, seals and connecting pipes suitable for air-cooled and water-cooled Porsche engines, useful for routine maintenance, engine rebuilds and restoration work.
Understanding OEMatch Filler Neck PartsOEM (Original Equipment Manufacturer) parts are made by the same company that produced your Porsche’s original filler neck parts.
OE (Original Equipment) refers to parts matching original specifications for the filler neck parts and may be supplied by alternative manufacturers. Aftermarket parts offer alternative options, sometimes with enhanced features or better value. OEMatch supplies non-OEM filler neck parts engineered as direct-fit alternatives to OEM parts, made to original-spec dimensions and tolerances for Porsche models.
These components form the filler neck assembly and are typically made from heat- and oil-resistant materials, with seals and O-rings that maintain pressure integrity and prevent contamination.
- Restores airtight sealing to prevent oil leaks and vapour loss.
- Supports clean, controlled oil refilling and reduces contamination risk.
- Replaces degraded pipes, seals and caps to maintain system pressure and reliability.
- Heat and vibration cause pipes and hoses to become brittle and crack.
- Seals and O-rings deteriorate from oil exposure and age, allowing vapour leaks.
- Residue and sludge build-up can impede sealing and lead to poor fitment.
Replacing worn filler neck components preserves oil system integrity, prevents leaks that can cause contamination or oil loss, and keeps servicing straightforward. Correct seals and properly formed filler pipes help the crankcase breathe as intended and support consistent engine operation across model years.
Advantages- Parts selected for compatibility with Porsche mounting points and service procedures.
- Materials chosen to resist oil, heat and corrosion for longer service life.
- Suitable for restoration and routine maintenance, covering both classic and modern applications.
