A fuel supply hose that carries pressurised fuel from the fuel pressure regulator to the diaphragm damper (fuel accumulator / damper) in the L-Jetronic injection system of certain classic Porsche 911 models. The damper helps smooth fuel pressure pulses and supply consistent fuel pressure to the injectors.
Fits:
Porsche 911 Carrera 1984 - 1989
Diagram ref no 19
This fuel line delivers a consistent, pressurised flow of fuel from the regulator to the damper without leaks or pressure loss. Its modern fuel-resistant construction ensures durability against petrol, vapour, and ethanol-blended fuels while maintaining stable fuel pressure for reliable injector performance and preventing issues such as hesitation or lean running. By replacing old, hardened, or cracked hoses, it restores the safety and efficiency of the fuel system. Designed with the correct internal diameter and fittings, it provides proper fuel delivery, smooths pressure fluctuations, and offers long-term resistance to heat, vibration, and chemical exposure for dependable operation on 911 engines.
Over time, fuel hoses deteriorate: rubber hardens, cracks or swells; internal layers degrade; fittings loosen. On a fuel-line this can lead to:
• Fuel leaks - hazard to engine bay and fire risk
• Pressure loss or instability - causing poor fuel delivery, misfires or rough running
• Permeation or fuel vapour leakage - potentially causing poor cold start, smell, or regulatory issues
Replacing the old hose with a fresh line ensures safe, leak-free fuel flow, correct pressure regulation, and reliable injector performance - essential for performance, reliability, and safety on an air-cooled Porsche 911.
You should replace this fuel line if:
• The original hose is cracked, swollen, hardened, or leaking
• There are signs of fuel smell or seepage around the regulator / damper area
• You’re performing fuel system maintenance, pressure regulator overhaul or damper replacement
• You are upgrading to modern fuels (higher ethanol content or aggressive blends)
• You notice fuel delivery issues - hesitation, poor idle, uneven fuel pressure

The overflow hose provides a vent path for fuel vapours and excess pressure from the fuel filler neck to the tank vent/evaporative system, preventing pressure buildup and aiding smooth refuelling without backflow or spills.
Fits:
Porsche 911 1978 - 1989
Porsche 964 1989 - 1994
Porsche 993 1994 - 1998
Diagram ref no 24
The hose fits between the fuel filler neck and the fuel tank vent/overflow outlet, allowing controlled relief of fuel vapours and pressure during refuelling and normal operation. A compromised or deteriorated hose can lead to fuel vapour leaks, poor venting, fuel smell at the rear of the vehicle, or difficulty refuelling due to trapped pressure.
This OE Match hose offers a direct replacement solution for restoration, maintenance, or repair when the original hose shows signs of age or damage.
Function:
• Ensures proper venting of fuel fumes and pressure from the filler neck
• Maintains correct fuel system breather operation
• Prevents fuel vapour leaks and associated odours
• Durable, fuel-resistant construction for long service life
The fuel filler overflow/vent hose plays a small but important role in maintaining proper fuel system behaviour. A cracked, hardened, or leaking hose can cause fuel vapour smells, trapped pressure that makes refuelling difficult, and potential environmental or safety issues. Replacing it with an OE Match hose restores correct venting and refuelling behaviour while helping keep the fuel system sealed and odour free.
When to replace:
• Visible cracking, swelling, or brittleness of the hose
• Noticeable fuel vapour smell near filler area
• Difficulty filling the tank (pressure backflow)
• During restoration or fuel system servicing
• If original hose shows age-related deterioration

This OE Match fuel pipe with “T” connection is a replacement fuel line used on Porsche 911 Carrera 3.2L models from 1984 to 1989. It is designed to match the original fuel pipe layout and provides a direct-fit connection within the engine fuel delivery system.
Fits:
Porsche 911 Carrera 3.2L 1984 - 1989
Diagram ref no 9
This fuel pipe fits in the rear engine fuel system on Porsche 911 Carrera 3.2L models. It connects between the fuel filter outlet and the two fuel injection rails, using the “T” connection to distribute fuel across the injection system, diagram reference number 9.
The fuel pipe carries fuel from the fuel filter outlet to the fuel injection rail connections. The integrated “T” connection allows fuel to be distributed correctly within the rear engine fuel system, helping maintain consistent fuel delivery to both fuel rails.
Functions
• Transfers fuel from the fuel filter outlet to the fuel injection rails
• Provides a “T” connection for correct fuel distribution
• Helps maintain stable fuel flow to the engine
• Supports reliable fuel injection system operation
• Replaces aged, cracked, leaking, or deteriorated fuel pipework
• Helps prevent fuel smell, seepage, or pressure loss from old lines
• OE Match replacement for original Porsche fuel pipe fitment
Why Replace This Part?
Original fuel pipes can deteriorate with age, heat, fuel exposure, and engine bay vibration. Rubber sections may harden, crack, swell, or leak, while fittings can corrode or become difficult to seal. A damaged fuel pipe can cause fuel smell, poor running, fuel pressure issues, or serious leak risks. Replacing the pipe helps restore safe and reliable fuel delivery.
When to replace:
• There is a fuel smell in or around the engine bay
• The fuel pipe is cracked, swollen, hardened, or leaking
• Fuel seepage is visible around the pipe or fittings
• The engine has poor running, hesitation, or fuel delivery issues
• The fuel filter, fuel rails, or injection components are being serviced
• The engine is being removed, rebuilt, or restored
• As preventative maintenance on an ageing original fuel line
