Overflow hose for fuel filler neck.
The overflow hose provides a vent path for fuel vapours and excess pressure from the fuel filler neck to the tank vent/evaporative system, preventing pressure buildup and aiding smooth refuelling without backflow or spills.

Fits:
Porsche 911 1978 - 1989
Porsche 964 1989 - 1994
Porsche 993 1994 - 1998

Diagram ref no 24

The hose fits between the fuel filler neck and the fuel tank vent/overflow outlet, allowing controlled relief of fuel vapours and pressure during refuelling and normal operation. A compromised or deteriorated hose can lead to fuel vapour leaks, poor venting, fuel smell at the rear of the vehicle, or difficulty refuelling due to trapped pressure.

This OE Match hose offers a direct replacement solution for restoration, maintenance, or repair when the original hose shows signs of age or damage.

Function:
•  Ensures proper venting of fuel fumes and pressure from the filler neck
•  Maintains correct fuel system breather operation
•  Prevents fuel vapour leaks and associated odours
•  Durable, fuel-resistant construction for long service life

The fuel filler overflow/vent hose plays a small but important role in maintaining proper fuel system behaviour. A cracked, hardened, or leaking hose can cause fuel vapour smells, trapped pressure that makes refuelling difficult, and potential environmental or safety issues. Replacing it with an OE Match hose restores correct venting and refuelling behaviour while helping keep the fuel system sealed and odour free.

When to replace:
•  Visible cracking, swelling, or brittleness of the hose
•  Noticeable fuel vapour smell near filler area
•  Difficulty filling the tank (pressure backflow)
•  During restoration or fuel system servicing
•  If original hose shows age-related deterioration

About Fuel Lines & Breather Hoses

Fuel Lines & Breather Hoses – Reliable Fuel Flow and Ventilation for Porsche Engines

Fuel lines and breather hoses are essential for maintaining safe, consistent, and efficient operation of your Porsche’s fuel and vapour management systems. The fuel lines transport petrol from the tank to the engine, while breather hoses manage pressure and vapour circulation within the fuel system, ensuring smooth refuelling and balanced performance.

At Design911, we supply a complete range of fuel lines, connectors, and breather hoses designed for long-lasting performance, accurate fitment, and durability under high-pressure and high-temperature conditions. Built from fuel-resistant rubber, reinforced composites, or stainless steel, each component ensures secure sealing, corrosion resistance, and reliable fuel delivery for both classic and modern Porsche vehicles.

Whether you’re servicing a classic 911, restoring a transaxle Porsche, or maintaining a performance 992, our manufacturer-quality components guarantee safe, efficient, and leak-free operation.

What Do Fuel Lines and Breather Hoses Do?

Fuel lines and breather hoses play crucial roles in maintaining a balanced and efficient fuel system.

Core Functions:

  • Fuel Lines: Safely transport pressurised fuel from the tank to the injectors or carburetors.
  • Breather Hoses: Equalise air pressure within the tank and prevent vapour lock or vacuum formation.
  • Vapour Management: Direct excess vapours back into the intake or carbon canister for emissions control.
  • System Integrity: Maintain proper sealing to avoid leaks, fumes, and performance loss.

A reliable fuel line and breather hose system is essential for optimal fuel delivery, safety, and emissions control.

Why Do Fuel Lines and Breather Hoses Fail?

Over time, these components are exposed to heat, vibration, and corrosive fuels, causing them to deteriorate.

Common Causes of Failure Include:

  • Cracking, hardening, or swelling due to ethanol-based fuels.
  • Internal corrosion or blockage from fuel contamination.
  • Age-related brittleness in rubber or plastic hoses.
  • Loose or leaking fittings reducing system pressure.       
  • External damage from abrasion or heat exposure.

When these parts fail, you may notice fuel odours, leaks, poor idling, or difficulty refuelling — all signs your Porsche’s fuel system needs attention.

Why Replace Fuel Lines and Hoses?

Replacing ageing or damaged lines and hoses ensures safe, efficient fuel flow and helps prevent leaks, vapour loss, and performance issues. Our precision-fit fuel lines and breather hoses are engineered to restore reliability while meeting modern material and performance standards.

Key Benefits:
  • Restores proper fuel flow and vapour control.
  • Prevents fuel leaks, odours, and emissions faults.
  • Improves safety and engine performance.
  • Constructed from modern, fuel-resistant materials.
  • Direct-fit installation for Porsche models across all generations.
  • Ideal for maintenance, restoration, and upgrades.

Proper maintenance ensures your Porsche’s fuel system remains clean, safe, and efficient — exactly as its performance heritage demands.

Highlights:
  • Comprehensive selection of Porsche fuel lines and breather hoses.
  • Precision-engineered for accurate fit and durability.
  • Resistant to ethanol, heat, and corrosion.
  • Supports stable fuel pressure and emissions control.
  • Compatible with classic and modern Porsche models.
  • Ideal for rebuilds, performance tuning, and preventive maintenance.
