🔌 Function

The washer distributes the clamping force of a fuel system fastener across a wider bearing surface and helps preserve joint integrity. Correct washer fitment supports a sealed, vibration-resistant connection in the fuel circuit.

⚠️ Common Signs of Failure

• Fuel weeping or seepage at the joint the washer seats against
• Visible distortion, flattening or cracking of the washer
• Corrosion, pitting or scoring on the sealing faces
• Fastener repeatedly loosening or failing to hold torque
• Surface indentation or galling on the mating component

🛠️ Service Notes

• Check you are fitting the same type of washer that came out — plain, hardened, sealing and locking washers are not interchangeable, and the wrong one either fails to seal or fails to hold
• Treat sealing washers on fuel, oil and coolant unions as single-use; they seal by deforming onto the faces, so a used one will not seal reliably a second time
• Clean the seating faces and make sure the washer sits flat and square, fully under the head or nut, before tightening — a washer trapped on a chamfer or edge will crush unevenly
• Tighten the fastener to the figure given in the workshop manual for your engine, and account for every washer on reassembly so none is left loose inside a housing or the engine bay
