- Porsche 911 1974-1977 2.7L / 1976-77 3.0 Carrera
Fuel Pressure Line – Pump to Fuel Accumulator
High-quality replacement fuel pressure line designed for Porsche 911 models from 1976 to 1977, connecting the fuel pump to the fuel accumulator.
This line is a critical component of the Bosch CIS
(Continuous Injection System), delivering pressurised fuel from the pump to the
accumulator, where pressure is stabilised before reaching the injection system.
Proper function is essential for smooth engine operation, reliable starting,
and consistent fuel delivery.

Diagram Ref No 11
Manufactured to OEM specifications, this fuel pressure line ensures precise fitment along with excellent resistance to fuel, heat, and high pressure—making it ideal for maintenance, repair, or restoration of classic Porsche 911 models.
Key Features
• Direct replacement fuel pressure line (pump to
accumulator)
• Suitable for Porsche 911 (1976–1977)
• Designed for CIS fuel injection systems
• Handles high-pressure fuel delivery
• Resistant to fuel, heat, and pressure
• OEM-style fit and performance
Function and Purpose
This fuel line is a vital part of the CIS fuel system.
It helps to:
• Deliver pressurised fuel from the pump to the accumulator
• Stabilise fuel pressure before distribution
• Support consistent engine starting and running
• Maintain proper fuel system operation
Why Replace Your Fuel Pressure Line
Fuel lines in CIS systems are subject to high pressure and heat over time.
Common issues include:
• Cracking or degradation of hose material
• Fuel leaks under pressure
• Loss of system pressure stability
• Hard starting or poor engine performance
Replacing the line restores safe and reliable fuel system function.

Fuel Line Clamp
Sold each - 4 required per car
Keep your Porsche's fuel system secure and correctly supported with this
Fuel Line Clamp. This clamp ensures the fuel lines remain firmly positioned,
protecting them from vibration, chafing and unnecessary movement.
Fits:
- Porsche 911 1965-1968 2.0L / 912 SWB (F)
- Porsche 911 1968-1971 2.2L LWB (F)

Although small in size, the fuel line clamp performs an essential role in the safe operation of the fuel system. It securely holds the fuel hose in its intended position, preventing it from rubbing against surrounding bodywork, engine components or sharp edges. By maintaining the correct routing of the fuel line, the clamp helps reduce stress on hose connections and minimises the risk of premature hose wear or fuel leaks.
Manufactured to OE Match standards, this replacement clamp offers factory-style fitment and durability, making it ideal for fuel system repairs, engine bay restoration projects and preventative maintenance on classic air-cooled Porsche 911 models.
What Does the Fuel Line Clamp Do?
The fuel line clamp is designed to securely retain the fuel hose while allowing the fuel system to operate safely under normal engine movement and vibration.
Correctly positioned fuel lines are essential to ensure:
- Fuel hoses cannot move excessively
- Hoses are protected from abrasion
- Connections remain under minimal stress
- Fuel lines are routed safely away from heat sources and moving components
- The fuel delivery system remains reliable and safe
While often overlooked during restoration, missing or damaged clamps can significantly reduce the lifespan of new fuel hoses.
Why Do Fuel Line Clamps Fail?
Fuel line clamps spend decades exposed to heat, moisture, road dirt, oil contamination and continual engine vibration. Over time they can become corroded, bent or weakened, reducing their ability to securely retain the fuel line.
During previous repairs, clamps are sometimes omitted altogether or damaged when fuel hoses are replaced. Incorrectly fitted aftermarket clamps may also fail to hold the hose in the correct position, allowing movement that can cause the fuel line to rub through over time.
Because the original clamps on many early Porsche 911 models are now more than fifty years old, replacement is often recommended whenever the fuel system is refurbished.
When Should the Fuel Line Clamp Be Replaced?
The fuel line clamp should be inspected whenever fuel hoses or other fuel system components are serviced.
Replacement is recommended if you notice:
- Corrosion or rust
- Bent or distorted clamp shape
- Loose or missing clamp
- Fuel hose movement
- Signs of hose chafing or abrasion
- Previous incorrect repairs
- During fuel hose replacement
- During engine bay restoration or full vehicle restoration
Replacing worn or missing clamps helps ensure the fuel system remains correctly routed, reducing the risk of hose damage and improving long-term reliability.
Porsche 911 Fuel System Components
The fuel system on every classic Porsche relies on more than just pumps, filters and hoses. Correct routing and secure support of every fuel line is equally important for maintaining safety, reliability and factory-correct operation.
Small hardware items such as fuel line clamps are frequently overlooked during restoration, yet they play a critical role in preventing vibration damage and ensuring the fuel system continues to perform as Porsche intended.
Whether carrying out a complete fuel system overhaul or replacing ageing fuel hoses, fitting new OE Match clamps helps complete the job to the highest standard.
Benefits of Replacing the Fuel Line Clamp
- Secures fuel hoses correctly
- Prevents unnecessary hose movement
- Reduces abrasion and chafing
- Helps minimise stress on hose connections
- Supports safe and reliable fuel system operation
- Restores factory-correct engine bay appearance
- Ideal during fuel hose replacement and restoration work
