Fuel filter flexible fuel line hose
Genuine Porsche OE flexible fuel line hose from the fuel filter to the hard fuel line for Porsche 928 models from 1980–1995. This original Porsche fuel hose forms part of the rear fuel delivery system and is used to connect the fuel filter outlet to the fixed hard fuel line, helping maintain safe and reliable fuel flow.

Fits:
Porsche 928 1980 - 1995

Diagram ref no 20

It is used on Porsche 928 models as part of the fuel pump / fuel filter / fuel accumulator / rear fuel line assembly. This hose provides the flexible connection between the fuel filter and rigid fuel pipework.

This part replaces earlier Porsche numbers: 92835605300, 92835605301

Functions
•  Connects the fuel filter to the hard fuel line
•  Carries fuel from the filter into the vehicle’s fuel delivery system
•  Provides a flexible connection between fixed fuel system components
•  Helps absorb vibration and movement between fuel line sections
•  Maintains correct fuel flow and pressure when properly fitted
•  Helps prevent leaks when used with correct fittings and installation
•  Provides OE Porsche fitment for the 928 fuel system
•  Replaces aged, cracked, leaking or damaged original fuel hose.

Why Replace This Part?
Fuel hoses age over time due to fuel exposure, heat, pressure and engine-bay or underbody conditions. The original flexible hose can harden, crack, swell, corrode at fittings or begin to seep fuel. Because this hose carries pressurised fuel, any leak or deterioration should be treated seriously. Replacing the hose with a Genuine Porsche OE fuel line helps restore the correct factory connection between the fuel filter and hard line, supporting safe fuel delivery and reliable operation.

When to Replace
•   This Part If there is any fuel smell near the rear fuel filter area
•   If the hose is cracked, brittle, swollen or visibly damaged
•   If fuel is seeping or leaking from the hose or fittings
•   During fuel filter, fuel pump or fuel accumulator replacement
•   During fuel system restoration or preventative maintenance
•   If the fittings are corroded, seized or damaged
•   When replacing old non-original or incorrectly routed fuel hose
•   Before recommissioning a Porsche 928 that has been stored long-term.

Where It Fits on the Car
This hose fits in the rear fuel system area, connecting the fuel filter to the hard fuel line. It is associated with the Porsche 928 fuel pump, fuel filter, fuel accumulator and rear fuel pipework assembly.

Engineered to OEM specifications, it delivers precise fitment and reliable sealing performance, making it an essential component for maintaining fluid system integrity across hydraulic, lubrication, and fuel systems. Ideal for servicing, repair, or restoration of both classic and modern Porsche models.

Key Features

• M14 banjo bolt for multiple Porsche applications
• Suitable for power steering, gearbox oil, and fuel systems
• Compatible with 911, 964, 924S, 928, and 944 models
• Designed for high-pressure fluid systems
• Ensures secure, leak-free connections
• OEM-style fit and specification
• Durable construction for long-term reliability

Function and Purpose

This banjo bolt is a critical fastening component used across several vehicle systems.

It helps to:
• Secure banjo fittings to power steering hoses
• Connect gearbox oil pipes for lubrication systems
• Fasten fuel line connections within the fuel system
• Maintain proper sealing under pressure
• Ensure consistent fluid flow and system efficiency

Why Replace Banjo Bolts

Over time, banjo bolts can degrade due to heat, pressure, and fluid exposure.

Common issues include:
• Fluid leaks (oil, fuel, or hydraulic fluid)

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.
