Fuel Supply Line, RHD.
Ensure reliable and safe fuel delivery in your Porsche with this genuine OEM fuel line. Designed for the Porsche 911 (964 series) and compatible models, this line is built to Porsche’s specification, delivering correct flow and pressure under demanding conditions. Whether it’s an aged original being replaced, or you’re refreshing your fuel-system as part of a restoration, this line is the correct direct replacement.
For Right Hand Drive Cars ONLY!

Fits:
  • Porsche 964 (911) C2 1989-91
  • Porsche 964 (911) C4 1989-91

Diagram Ref No 12

What This Product Does:

  • This fuel line serves as a supply / delivery line in the fuel system of the vehicle — it carries fuel (often from the tank or pump assembly) to a required downstream point (for example to injectors, filter, or engine compartment) under appropriate pressure and flow conditions.
  • Because it is an OEM-engineered line, the material, routing, fittings, and mounting clips are designed to match Porsche’s specification of that era — ensuring correct pressure resistance, vibration resistance, fuel type compatibility (petrol, possibly lead-free or additives), and correct safety margins.
  • The correct fuel line helps maintain fuel delivery without leaks, maintains correct flow/pressure, prevents vaporisation or fuel starvation, and helps ensure safe and reliable engine operation.

Symptoms And When To Replace:
  • Fuel smell or visible leak: Any aroma of petrol around the engine bay or underside, or visible wetness on or around the line’s fittings.
  • Cracks, bulges or deterioration of the line: Over time hoses/lines degrade from heat/vibration/fuel exposure. If you see exterior damage or soft spots, it’s a red flag.
  • Fuel pressure issues: If the fuel delivery is erratic, engine sputters under load or you suspect a drop in supply, the line or its fittings might be compromised.
  • Hard starts or hesitation under acceleration: Especially in high-demand situations the supply line may fail to deliver properly.
  • Vehicle overhaul or restoration: If the car is older and the original fuel system components are aged, installing a new line is a preventative measure.

Why Replacement Matters:
  • Safety: Fuel lines operate under pressure and handle flammable fuel. A failure can lead to leaks, fire risk or engine shutdown, replacing the line ensures design safety margins.
  • Performance & reliability: Proper line ensures correct fuel supply, no pressure drop, no vapor lock or starvation issues which can degrade performance or lead to engine damage.

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.
