The fuel tank cap plays an important role in maintaining the integrity of the fuel system by sealing the tank correctly and supporting the operation of the vehicle's fuel vapour management system. Over time, locks can seize, keys may be lost, seals can harden or crack, and the cap itself may become damaged through wear or corrosion. Replacing a worn or faulty cap helps ensure the fuel system remains properly sealed and protected. This OE Match lockable fuel tank cap is ideal for routine maintenance, repairs, and Porsche restoration projects.  

What This Product Does:

• Provides a secure seal for the fuel tank.
• Helps prevent fuel evaporation and contamination.
• Protects against unauthorised access to the fuel tank.
• Supports correct operation of the fuel system.
• Restores the original appearance and functionality.
• Replaces worn, damaged, or missing fuel caps.
• Provides an OE-style fit and dependable performance.

Symptoms Of Wear Or Failure:

• Fuel smell around the filler neck.
• Damaged, cracked, or missing fuel cap.
• Lock mechanism seized or difficult to operate.
• Missing or broken keys.
• Worn or hardened sealing gasket.
• Loose-fitting cap that does not seal correctly.
• Corrosion or physical damage to the cap.
• Age-related deterioration of the original component.

Why Replacement Matters:

• The fuel tank cap is essential for sealing the fuel system, helping to prevent fuel vapour loss, contamination, and unauthorised access to the fuel tank. A worn or damaged cap can compromise the fuel system seal, allowing fuel odours, moisture, dirt, or debris to enter while also reducing the effectiveness of the vehicle's fuel vapour control system.
• Replacing the lockable fuel tank cap restores a secure seal, reliable locking function, and proper protection for the fuel system. Manufactured as a direct replacement and produced to OE-style specifications, this OE Match component provides the correct fit, dependable performance, and long-lasting durability, making it an excellent choice for Porsche maintenance, repairs, and restoration projects.

Maintain a secure, leak-free seal for your Porsche's fuel system with this OE Match Fuel Tank Cap Seal, manufactured as a direct replacement. Produced to OE-style specifications, this rubber sealing ring fits between the fuel filler cap and filler neck, helping to prevent fuel vapours, moisture, and contaminants from entering or escaping the fuel tank while ensuring the cap seals correctly.

Fits:

• Porsche 356 1950-55

Over time, the original seal can become hardened, flattened, cracked, or perished through exposure to fuel, heat, and age. A deteriorated seal may reduce the effectiveness of the fuel cap, potentially allowing fuel odours, moisture ingress, or vapour leaks. Replacing the fuel tank cap seal restores the correct sealing performance and helps maintain the integrity of the fuel system. This OE Match component is ideal for routine maintenance, fuel system repairs, and Porsche restoration projects.  

What This Product Does:

• Creates a secure seal between the fuel cap and filler neck.
• Helps prevent fuel vapour leaks.
• Reduces the risk of moisture and dirt entering the fuel tank.
• Maintains the correct sealing performance of the fuel filler cap.
• Replaces hardened, cracked, or perished original seals.
• Supports reliable fuel system operation.
• Provides an OE-style fit and dependable quality.

Symptoms Of Wear Or Failure:

• Cracked, split, or perished rubber seal.
• Flattened or compressed sealing surface.
• Fuel odours around the filler cap.
• Fuel cap no longer sealing securely.
• Signs of moisture or contamination around the filler neck.
• Visible deterioration caused by age or fuel exposure.
• Loose-fitting fuel cap despite being correctly tightened.
• Evidence of vapour leakage around the fuel filler.

Why Replacement Matters:

• The fuel tank cap seal plays a vital role in maintaining the integrity of the fuel system by creating a tight seal between the fuel cap and the filler neck. A worn or deteriorated seal can allow fuel vapours to escape, permit contaminants or moisture to enter the fuel tank, and reduce the effectiveness of the fuel cap.
• Replacing the seal restores the correct sealing performance, helping to protect the fuel system, reduce fuel odours, and maintain reliable operation. Manufactured as a direct replacement and produced to OE-style specifications, this OE Match fuel tank cap seal provides the correct fit, dependable quality, and long-lasting durability, making it an excellent choice for Porsche maintenance, fuel system repairs, and restoration projects.

Fuel tank cap, not lockable. Made of metal.
It’s a metal fuel cap (without lock) that provides a secure, traditional-style closure for the fuel tank filler neck, replicating the look and fit of the original Porsche part. 

Fits:
Porsche 356 B/C 1.6L 01/1959 - 12/1965
Porsche 911 2.0L-3.0L 10/1963 - 07/1977
Porsche 914/6 2.0L 11/1969 - 12/1973

The fuel tank cap seals the fuel filler neck to prevent fuel evaporation, contamination, and spillage. It forms a barrier between the fuel tank and the outside environment, helping preserve fuel quality while reducing the risk of leaks.

When installed, the fuel cap threads or seats into the filler neck and creates a tight, secure closure for the fuel tank. It keeps dirt, water, and debris out of the fuel system, helping maintain engine performance and reliability. Its metal construction provides durability and a classic aesthetic in line with the original vehicles’ styling.

The fuel cap is a small but essential component in your vehicle’s fuel system. A worn or missing cap can lead to:
• Fuel evaporation and loss
• Water or dirt entering the tank
• Fuel system contamination
• Fuel odour and reduced efficiency
Replacing worn or damaged caps with a high-quality fuel cap ensures secure sealing, preserves authenticity, and helps maintain proper fuel system operation — especially for classic car restorations and daily driving.

Replace the fuel tank cap if you notice:
• Fuel smell near the filler area
• Loose or ill-fitting cap
• Visible corrosion, dents, or damaged threads
• Water entering the fuel filler neck
• Restoring a classic Porsche to original condition
