Why Replacement Matters

Fuel pipes can deteriorate through age, corrosion, heat cycles or damage caused during previous repairs. Any suspected leak requires immediate investigation because escaping fuel or vapour can create a fire risk. When fitting the replacement line, examine the adjacent clamps, mountings, seals and connected pipework, then test the completed system for leaks using the correct workshop procedure.

FAQs

• Is this return line for left-hand-drive vehicles?
  Yes. The supplied application and catalogue notation identify it for the left-hand-drive pipework arrangement.
• Why are two production notes shown?
  The same part number appears against both /LL -94 and /LL 95- groups in the 993 fuel-system catalogue.
• Should other components be checked during installation?
  Inspect the retaining clamps, rubber mountings, seals and neighbouring fuel lines while they are accessible.
• Can the car be driven if a fuel leak is suspected?
  No. Do not start or drive the vehicle until the fuel system has been inspected and repaired by a suitably qualified technician.
