Fuel Pipe Connector.

The Porsche Fuel Pipe Connector is a genuine OEM connecting piece designed for the fuel delivery system in classic Porsche models, including the 924 and 944. This small but vital component links sections of fuel pipe or hose, ensuring a secure and leak-free connection within the fuel system.
Over time, connectors can weaken, corrode, or crack, leading to fuel leaks and loss of pressure. Replacing it with this OEM Porsche connector restores system integrity, prevents dangerous leaks, and ensures your engine receives the correct fuel pressure for smooth performance.

Fits:

• Porsche 924 2.0L 1976-79
  
• Porsche 924 2.0L 1980-85
  
• Porsche 924S 2.5L 1986-87 
• Porsche 924S 2.5L 1988 
• Porsche 944 2.5L 8V 1982-85
  
• Porsche 944 Turbo 2.5L 8V 1985-88
  
• Porsche 944 Turbo S 2.5L 8V 1988>>
  
• Porsche 944S2 3.0L 16V 1989-91
  
• Porsche 944 Turbo 2.5L 8V 1989-91

What This Product Does:
It’s a small but essential connector in the fuel feed / fuel line system. It joins sections of fuel pipe or hose — often between the fuel pump, fuel filter, accumulator, or between pipe and hose segments.

Symptoms Of A Faulty Or Failing Fuel Pipe Connector:
If this connector is worn, damaged, or leaking, common symptoms will include:

• Fuel smell around the engine bay or under the car, especially near where this connector is installed.
• Liquid fuel leaks visible around the connector or dripping when the engine is running / fuel system is pressurized.
• Poor fuel pressure, which can lead to rough running, hesitation, or weak acceleration.
• Possibly difficulty starting if fuel supply is compromised.
• Visible damage or corrosion to the connector — cracked plastic or metal, worn threads, or loose hose / pipe connections.

 
Why Replacement Matters:
Even though it’s a small part, it’s critical:

• Fuel delivery depends on all connectors and lines being sealed and strong. A faulty connector can compromise the whole fuel feed.
• Leaks are dangerous (fire risk) and waste fuel.
• Loss of pressure or leaks can lead to poor engine performance, misfires, or engine stalling.
• Using a genuine part like this one ensures correct fit, strength, sealing finish, and avoids fitment mismatches or leaks.

What This Product Does

This fuel hose connects directly to the fuel filter and forms part of the vehicle's fuel delivery system. It provides a replacement for an ageing, damaged or leaking original hose while retaining the specified connection arrangement.

Functions

• Transfers fuel from the filter into the downstream fuel line
• Maintains a sealed connection within the fuel delivery system
• Replaces an original hose affected by age or deterioration
• Supports refurbishment of the fuel filter and line assembly

Technical Details

• Connects directly to the fuel filter
• Quantity used per vehicle: one
• Diagram ref no 12

Symptoms of Fault

• Fuel odour after the vehicle has been parked
• Visible cracking, hardening or deterioration of the hose
• Dampness around the hose ends or connections
• Evidence of fuel seepage near the filter
• Long cranking, hesitation or inconsistent running where fuel delivery is affected

Why Replacement Matters

Fuel hoses are exposed to age, vibration, pressure cycles and changes in fuel composition. Renewing a hose that shows cracking, seepage or damaged fittings helps restore the integrity of the fuel circuit. Check the surrounding filter, hard line, seals and connections during installation, and test the system carefully for leaks before returning the vehicle to service.

FAQs

• Where is this hose fitted?
  It attaches directly to the fuel filter and connects it to the downstream fuel line.
• When should the hose be replaced?
  Replacement is advisable if the hose is cracked, hardened, damp, leaking or has deteriorated fittings.
• Should other components be inspected?
  Yes. Examine the filter connections, adjoining lines, fixings and sealing points for corrosion, damage or leakage.
• Is professional installation recommended?
  Fuel-system work requires careful depressurisation, correct fitting and leak testing. Installation should be completed or checked by a competent technician.
