Product Information
Product Information
Fuel Pipe Connector.

The Porsche Fuel Pipe Connector is a genuine OEM connecting piece designed for the fuel delivery system in classic Porsche models, including the 924 and 944. This small but vital component links sections of fuel pipe or hose, ensuring a secure and leak-free connection within the fuel system.
Over time, connectors can weaken, corrode, or crack, leading to fuel leaks and loss of pressure. Replacing it with this OEM Porsche connector restores system integrity, prevents dangerous leaks, and ensures your engine receives the correct fuel pressure for smooth performance.

Fits:

  • Porsche 924 2.0L 1976-79
  • Porsche 924 2.0L 1980-85
  • Porsche 924S 2.5L 1986-87 
  • Porsche 924S 2.5L 1988 
  • Porsche 944 2.5L 8V 1982-85
  • Porsche 944 Turbo 2.5L 8V 1985-88
  • Porsche 944 Turbo S 2.5L 8V 1988>>
  • Porsche 944S2 3.0L 16V 1989-91
  • Porsche 944 Turbo 2.5L 8V 1989-91

What This Product Does:
It’s a small but essential connector in the fuel feed / fuel line system. It joins sections of fuel pipe or hose — often between the fuel pump, fuel filter, accumulator, or between pipe and hose segments.

Symptoms Of A Faulty Or Failing Fuel Pipe Connector:
If this connector is worn, damaged, or leaking, common symptoms will include:
  • Fuel smell around the engine bay or under the car, especially near where this connector is installed.
  • Liquid fuel leaks visible around the connector or dripping when the engine is running / fuel system is pressurized.
  • Poor fuel pressure, which can lead to rough running, hesitation, or weak acceleration.
  • Possibly difficulty starting if fuel supply is compromised.
  • Visible damage or corrosion to the connector — cracked plastic or metal, worn threads, or loose hose / pipe connections.

 
Why Replacement Matters:
Even though it’s a small part, it’s critical:

  • Fuel delivery depends on all connectors and lines being sealed and strong. A faulty connector can compromise the whole fuel feed.
  • Leaks are dangerous (fire risk) and waste fuel.
  • Loss of pressure or leaks can lead to poor engine performance, misfires, or engine stalling.
  • Using a genuine part like this one ensures correct fit, strength, sealing finish, and avoids fitment mismatches or leaks.

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.
