Fuel pipes carry gasoline from the tank to the engine. Three types of fuel pipes have been used in the design and manufacture of vehicles.

  • Metallic tubes
  • Rubber hoses
  • polyamide tubes

Why is the use of metal tubes and rubber hoses in the design and production of world-day vehicles has become obsolete?

  1. The use of fasteners and rubber in the connections of the gasoline route leads to increased risk of leakage.
  2. High ultimate cost: The production costs of these components are high according to the standards of the day and the cost of raw materials of these components.
  3. Low resistance to impact: These tubes are vulnerable to impact and are likely to fracture when exposed to a high barrier.
  4. High rubber permeability
  5. Low corrosion resistance in environmental conditions compared to polyamide pipes

The use of multi-layer polyamide pipes has also the following advantages:

  1. Polyamide tubes are easily shaped and are malleable for the fuel transmission to the engine.
  2. The presence of various layers of materials in these pipes, including inhibitor materials in the middle layers, reduces the permeation of gasoline into the environment.
  3. The use of fast connections in gasoline passages, in addition to the ease of assembly, also increases the safety of the piece.
