Fuel-Injection pipe support bracket.
The Injector pipe bracket is a precision-manufactured support bracket designed to secure the fuel injection or injector supply pipes on Porsche 911 models. This bracket locates the injector line firmly, prevents vibration-induced wear, ensures correct routing, and helps maintain system integrity. Its replicates the factory form, fits directly into the mounting points, and offers dependable durability for OE-type fitment.

Fits:
Porsche 911 1969 - 1977

Diagram ref no 11

• Function: Secures injection or fuel supply pipe to head or pump assembly
• Position: Engine – injection system, cylinder head / injection pump fitting
• Benefits: Reinforces fuel-injection plumbing, prevents vibration wear, ensures proper alignment

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 Line For Warm Up Valve.

The Fuel Line for Warm Up Valve is an OEM-spec Porsche fuel line designed for classic air-cooled Porsche 911 models equipped with Bosch CIS / K-Jetronic mechanical fuel injection. This line connects to the warm-up valve / warm-up regulator and plays an essential role in maintaining correct fuel routing and pressure control during cold starts and engine warm-up.

Fits:

• Porsche 911 T-K 1972-1973 2.4L WB (F)
• Porsche 911 1974-1976 2.7L / 1976 3.0 Carrera

Fits On To Diagram Ref No 28

In CIS fuel systems, the warm-up regulator helps manage control pressure so the engine can start cleanly when cold and transition smoothly to normal running conditions as temperatures rise. A properly functioning fuel line is critical to ensure stable pressure and leak-free operation. Over time, original fuel lines can degrade from age, heat exposure, and vibration, leading to cracking, seepage, or weakened fittings.

What This Product Does:

• Carries fuel to/from the warm-up valve / warm-up regulator
  
• Helps regulate control pressure in CIS injection systems
  
• Supports smooth cold start operation and warm running performance
• Ensures fuel is delivered through the correct metering path
• Maintains leak-free, correct routing using OEM-style fittings

Symptoms Of A Failing Fuel Line:

• Fuel smell in the engine bay
• Visible fuel seepage or dampness around fittings
• Cracked or aged line material (especially on older CIS cars)
• Hard starting or poor cold running (if pressure is affected)
• Rough idle during warm-up
• Potential fuel leaks creating a fire risk

Why Replacement Matters:

• Prevents dangerous fuel leaks in the engine bay
  
• Maintains correct CIS fuel pressure regulation for proper drivability
• Supports reliable cold starts and smoother warm-up operation
• Helps avoid engine running issues caused by pressure loss
• Preserves safety and originality in classic Porsche maintenance

Return fuel line in centre tunnel. 
This is an original Porsche metal fuel line routed through the centre tunnel of early 911/912 models. It carries fuel or return flow as part of the vehicle’s original fuel-system layout.

Fits:
Porsche 911 E / 911S - 1969 to to 1971 (2 required per car)
Porsche 911T 1969 to 1969 (1 required per car)
Porsche 911 - 1972 to 1973 (1 required per car)

Diagram ref no 25 (for 911T, 911) / 18 (for 911E/S)

Runs from the fuel tank area through the centre tunnel; often termed a “control line” or “return line.”

With age the original metal line can suffer from corrosion, fatigue or damage - leading to fuel leaks or vapour loss, which pose safety risks. Installing the correct genuine Porsche line ensures the system maintains its original routing, integrity and reliable fuel delivery.

Return fuel line in centre tunnel. 
Metal fuel line that runs the length of the centre tunnel.

Fits:
Porsche 911 E / 911S - 1969 to to 1971 (2 required per car)
Porsche 911T 1969 to 1969 (1 required per car)
Porsche 911 - 1972 to 1973 (1 required per car)

Diagram ref no 25 (for 911T, 911) / 18 (for 911E/S)

This metal fuel line provides reliable fuel-circuiting within the vehicle’s structure, directing fuel return or feed through the centre tunnel. It must maintain integrity under fuel pressure, vibration and heat, while resisting corrosion for long service life.

Over time, the original fuel lines in the centre tunnel can deteriorate due to vibration, fuel exposure, and age. This can lead to leaks, vapour loss, or safety risks. Replace the fuel line when:
 • Corrosion or rust is visible on the metal surface.
 • You notice fuel odour or damp spots near the tunnel area.
 • The line shows signs of wear, cracking, or deformation.
 • Performing a full restoration, engine rebuild, or fuel-system refresh.

Installing a high-quality new fuel line ensures proper routing, durable materials, and leak-free operation - restoring the safety and reliability of your Porsche’s fuel system.

Fuel Pressure Line – To Fuel Accumulator

High-quality replacement fuel pressure line designed for Porsche 911 T-K, 911, and 911S models equipped with Bosch CIS (K-Jetronic) fuel injection systems.

This line connects the fuel system to the fuel accumulator, a critical component responsible for stabilising fuel pressure and ensuring smooth engine operation—particularly during starting and transient load conditions.

Fits:

• Porsche 911 T-K 2.4L - 1972-73
• Porsche 911 2.7L - 1974
• Porsche 911 S 2.7L - 1974

Diagram ref no 18

As part of the high-pressure CIS fuel network, this line plays a vital role in maintaining consistent fuel delivery across the entire system.

Manufactured to OEM specifications, it provides precise fitment and durability, making it ideal for maintenance, repair, or full fuel system restoration.

Key Features

• Direct replacement fuel pressure line to accumulator
• Suitable for Porsche 911 T / 911 / 911S (CIS systems)
• Designed for high-pressure fuel delivery
• OEM-correct routing and fitment
• Resistant to fuel, heat, and pressure
• Ideal for single replacement or full system rebuild

Part of a Complete CIS Fuel System

This fuel pressure line operates within a fully integrated CIS fuel delivery system, including:

• Fuel pump
• Fuel accumulator
• Fuel metering head
• Injector lines (to each cylinder)
• Fuel return lines
• Fuel injectors

Each component is interconnected—meaning performance issues are often linked across multiple parts.

Why Replace Fuel Pressure Lines as a System

Due to age and operating conditions, CIS fuel lines often degrade together.

Common reasons to replace include:

• Pressure loss or inconsistent fuel delivery
• Hard starting or poor warm running
• Fuel leaks under pressure
• Age-related cracking or internal restriction

For best results, inspect or replace multiple lines together to restore full system performance.
