🔧 Product Description

Genuine Volvo Penta o-ring from the Fuel System group, listed for 17 applications on D series engines. It is a fuel side sealing ring rather than a coolant or oil one, so match it to the fuel component being serviced rather than to a similar looking ring from another circuit.

⚙️ Key Features

  • Fuel System group
  • 17 applications on the D series
  • Fuel side sealing ring

🔌 Function

Seals a fuel joint by compressing into its groove, holding the pressure and keeping fuel from escaping past the face.

⚠️ Common Signs of Failure

  • Fuel weeping or a diesel smell around the joint
  • Air drawn into the fuel system, giving hard starting or a rough idle
  • Ring found flattened, hardened, nicked or swollen on removal
  • Diesel staining or a clean washed streak on the casting below the joint
  • Loss of prime after the engine has stood

🛠️ Service Notes

  • Fit new every time the joint is opened, as a used o-ring has taken the shape of its groove
  • Check the groove and the sealing face for nicks and burrs, since a scored face will leak past a new ring
  • Bleed the fuel system and check for leaks under pressure after fitting

📦 Condition

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