🔌 Function

Draws the fuel line joint together and holds the sealing sleeve tight against its seat.

⚠️ Common Signs of Failure

  • Fuel weeping at the union despite tightening
  • Nut thread stripped or galled
  • Hex rounded off from a slipping spanner
  • Nut corroded onto the fitting
  • Air drawn into the fuel system, giving hard starting

🛠️ Service Notes

  • Renew sleeve 6634735 with the nut when the joint is remade
  • Tighten to a firm seal rather than as hard as possible, as over-tightening cones the sealing faces
  • Bleed the fuel system after any line is opened

📦 Condition

  • Genuine Volvo Penta part
  • Brand new
  • Supplied in original or equivalent packaging
