This Fuel-Injector Pipe Bracket is a support bracket designed to secure the fuel injection or supply pipes on Porsche 911 models (1969–1977). It firmly anchors the injector lines in place, prevents vibration-induced wear, and ensures correct pipe routing for long-term system integrity.
Fits:
Porsche 911 1969 - 1977
Diagram ref no 11
Manufactured to match the original Porsche design, this bracket installs directly into the factory mounting points and provides durable, OE-type reliability.
• Function: Secures injection or fuel supply pipe to cylinder head or injection pump assembly
• Position: Engine – fuel injection system / cylinder head area
• Benefits: Reinforces fuel line routing, minimizes vibration wear, and maintains proper alignment
Fuel-injection brackets are constantly exposed to engine vibration, heat, and stress. Over time, the original parts can become loose, corroded, or bent, leading to unstable pipe support or even potential fuel leaks.
Replace this bracket when:
• Performing a fuel-injection system service or rebuild
• You observe loose, vibrating, or misaligned injection lines
• The original bracket shows corrosion or distortion
• Re-installing injection plumbing after cylinder head or pump removal

Fuel-injection piping and brackets are subject to constant engine vibration, heat, and mechanical stress. Over time the original bracket may become loosened, corroded, bent or fatigued, resulting in unstable pipe support, potential wear, or fuel-leak risk.
Replace this bracket when:
• Performing a fuel-injection system repair or service
• You observe loose or vibrating injection lines
• The original bracket shows corrosion, bending or missing alignment
• Re-installing injection plumbing after head or pump removal
Installing a new Injector Pipe Bracket ensures secure pipe routing, reduced vibration wear, and continued safe operation of the injection system in your Porsche 911.

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?
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.
