Fuel Tank Strap Kit.

The OE Match Fuel Tank Strap Kit is a premium-quality replacement mounting kit designed to securely support and retain the fuel tank on compatible classic Porsche models. Manufactured to OE specifications for fit, strength and durability, this complete kit includes fuel tank retaining straps and the associated mounting hardware required for a safe and secure installation, ensuring the fuel tank remains correctly positioned under all driving conditions.

Fits:

  • Porsche 356 1950-55
  • Porsche 356A 1955-59
  • Porsche 356B 1959-63
  • Porsche 356C 1963-65

Manufactured from high-strength automotive-grade steel with a durable corrosion-resistant zinc-plated finish, the straps are engineered to withstand the weight of a full fuel tank, continual road vibration, moisture, road salt and changing temperatures. Designed to replicate the original Porsche dimensions and mounting points, the kit provides direct OE-style fitment, making it ideal for fuel tank replacement, restoration projects, chassis refurbishment and preventative maintenance.

What This Product Does:
  • Securely supports and retains the fuel tank.
  • Prevents unwanted fuel tank movement during driving.
  • Maintains correct alignment of the fuel tank and mounting points.
  • Reduces stress on fuel lines, filler necks and associated components.
  • Minimises vibration transmitted through the fuel tank assembly.
  • Replaces worn, corroded or damaged fuel tank mounting hardware.
  • Restores factory fuel tank mounting performance.
  • Forms an essential part of the vehicle's fuel system support assembly.

Symptoms Of Wear Or Failure:
  • Corroded or heavily rusted fuel tank straps.
  • Loose or unstable fuel tank.
  • Rattling or knocking noises from beneath the vehicle.
  • Bent or distorted retaining straps.
  • Cracked or weakened mounting hardware.
  • Excessive movement of the fuel tank during driving.
  • Difficulty securing the fuel tank correctly.
  • Visible deterioration caused by corrosion or age.
  • Increased stress on fuel hoses or fuel lines.
  • MOT or inspection failure due to insecure fuel tank mounting.

Why Replacement Matters:
  • Fuel tank straps and their mounting hardware are continuously exposed to harsh environmental conditions, including water, road salt, dirt and constant vibration. Over time, corrosion and metal fatigue can weaken the straps and fixings, reducing their ability to securely support the fuel tank.
  • A weakened mounting system can allow the fuel tank to move excessively, placing additional strain on fuel hoses, filler necks and mounting points. If left unresolved, this movement can lead to premature wear, fuel system damage and, in severe cases, compromise vehicle safety.
  • Replacing worn or corroded components with the OE Match Fuel Tank Strap Kit restores secure fuel tank retention and factory-correct installation. Manufactured to OE standards using premium-quality corrosion-resistant materials, this complete kit provides factory-style fitment, exceptional strength and long-lasting durability, helping preserve the safety, reliability and originality of your Porsche.

  • Excessive movement of the fuel tank while driving.
  • Visible deterioration caused by age or corrosion.
  • Increased stress on fuel lines or filler neck connections.
  • MOT or vehicle inspection failure due to insecure fuel tank mounting.

Why Replacement Matters:

  • Fuel tank straps are continually exposed to moisture, road salt, dirt and vibration beneath the vehicle. Over time, corrosion and metal fatigue can weaken the strap, reducing its ability to safely support the fuel tank. A weakened or damaged strap can allow the tank to move excessively, placing unnecessary strain on fuel hoses, filler necks and mounting hardware.
  • If left unresolved, excessive fuel tank movement can lead to premature wear of fuel system components, unwanted noise and, in severe cases, compromise the security of the fuel tank. Replacing worn straps is an important part of maintaining the safety and reliability of the vehicle.

About Fuel Tank & Parts

Fuel Tanks & Components – Reliable Fuel Storage and Performance for Porsche Vehicles

Your Porsche’s fuel tank is the foundation of its fuel system, storing and supplying petrol safely to the engine. Working alongside essential components such as tank straps, seals, fittings, filters, and breather valves, the fuel tank ensures efficient flow, pressure stability, and safety in every driving condition.

At Design911, we offer a wide range of fuel tanks and replacement parts designed for Porsche models across generations — from air-cooled classics to high-performance GT cars. Each component is built from corrosion-resistant materials to deliver long-lasting durability, leak-free sealing, and reliable performance.

Whether you’re restoring a vintage 911 or maintaining a modern Porsche, our manufacturer-quality tanks and fittings provide superior build quality and exact fitment for peace of mind and long-term reliability.

What Do Fuel Tanks and Their Components Do?

The fuel tank stores petrol and ensures safe, uninterrupted supply to the fuel pump and injection system. Supporting parts such as hoses, straps, seals, and sensors maintain pressure balance and structural integrity.

Core Functions:

  • Stores and protects fuel from contamination and evaporation.
  • Provides consistent delivery to the fuel pump and injectors.
  • Ventilation and pressure regulation via breather systems.
  • Ensures safe operation through leak prevention and corrosion resistance.

A properly functioning tank and its fittings are vital for engine performance, efficiency, and safety — especially in performance-focused Porsche engines.

Why Do Fuel Tanks and Components Fail?

Fuel tanks and fittings are constantly exposed to harsh conditions — fuel vapours, moisture, and road debris — all of which can lead to deterioration over time.

Common Causes of Failure Include:

  • Corrosion and rust due to moisture and ethanol-blended fuels.
  • Cracked hoses or fittings, leading to leaks and pressure loss.
  • Deteriorated seals or gaskets causing vapour emissions or odours.
  • Physical damage from road debris or accidents.
  • Internal contamination from old fuel or sediment buildup.

Symptoms of fuel tank issues include fuel smells, visible leaks, poor pressure, or inconsistent fuel delivery, all of which affect performance and safety.

Why Replace with Precision-Engineered Fuel Tanks and Parts?

Upgrading or replacing damaged or aged components restores the integrity and safety of your Porsche’s fuel system. Our precision-fit, corrosion-resistant tanks and parts are designed to maintain proper fuel delivery and ventilation while preventing leaks and emissions.

Key Benefits:

  • Restores reliable fuel storage and pressure regulation.
  • Prevents leaks, vapour loss, and performance issues.
  • Improves fuel efficiency and drivability.
  • Constructed from high-grade steel or composite materials.
  • Direct-fit replacement for classic and modern Porsche models.
  • Long-lasting protection against corrosion and vibration damage.

Essential for restorations and repairs, these components help ensure your Porsche continues to perform with precision and confidence.

Highlights:

  • High-quality Porsche fuel tanks and replacement components.
  • Corrosion- and pressure-resistant construction.
  • Direct-fit compatibility for a wide range of Porsche models.
  • Ensures safe, efficient fuel storage and delivery.
  • Ideal for restorations, upgrades, and maintenance projects.
  • Designed for long-term reliability and performance.
