⚙️ Key Features

  • Designed for diesel fuel, heat and engine vibration
  • Full model and serial confirmation required

🔌 Function

The hose transfers diesel fuel through the designated D12 supply, return or leak-off circuit while absorbing engine movement.

⚠️ Common Signs of Failure

  • Diesel leakage or fuel smell
  • Hose cracking, swelling or chafing
  • Restricted fuel flow and loss of power

🛠️ Service Notes

  • Renew the sealing washers, O-rings or seals that belong to the connection rather than reusing them, and do not put jointing compound on a fuel union to cure a weep
  • Fit the hose without twist, and support and clip it along its run so it cannot chafe or hang its own load on the end fittings
  • Keep the hose clear of hot exhaust and moving parts, and cap the open ends while working so nothing gets into the fuel system
  • Tighten unions to the figure given in the workshop manual for your engine — overtightening a fuel fitting distorts the seat and makes the leak permanent
  • Bleed the fuel system afterwards, then run the engine and check the whole run for weeps under working pressure, with no ignition sources near and a means of containing spilt fuel to hand
