Diagram Ref No 15

The fuel cap seal is a small but essential component that ensures the fuel tank remains properly sealed. Over time, exposure to fuel, heat, and the elements can cause the original rubber seal to harden, crack, flatten, or lose its elasticity. A deteriorated seal can allow fuel vapours to escape, potentially triggering emissions faults and reducing the efficiency of the EVAP system. This OE Match replacement restores reliable sealing performance, making it an ideal choice for routine maintenance and classic Porsche restoration projects.  

What This Product Does:

• Creates an airtight seal between the fuel cap and filler neck.
• Helps prevent fuel vapour leaks.
• Supports correct operation of the EVAP emissions system.
• Prevents dirt and moisture from entering the fuel tank.
• Helps maintain correct fuel system pressure where applicable.
• Restores reliable sealing performance.
• Provides an OE-style fit and long-lasting durability.

Symptoms Of Wear Or Failure:

• Cracked, hardened, or flattened fuel cap seal.
• Fuel smell around the filler area.Fuel vapour leaks.
• Illuminated engine management or emissions warning light.
• EVAP system fault codes.
• Poor sealing between the fuel cap and filler neck.
  
• Visible deterioration of the rubber seal.
• Age-related deterioration of the original component.

Why Replacement Matters:

• The fuel cap seal is a vital component that helps maintain a sealed fuel system by preventing fuel vapours from escaping and contaminants from entering the fuel tank. A worn or damaged seal can lead to fuel odours, emissions-related warning lights, and reduced EVAP system efficiency.
• Replacing a deteriorated fuel cap seal restores the proper seal between the fuel cap and filler neck, helping to maintain fuel system integrity and emissions performance. Manufactured to OE-style specifications, this OE Match replacement provides the correct fit, dependable sealing, and long-lasting durability, making it an excellent choice for Porsche maintenance and restoration.
