⚠️ Common Signs of Failure

• Oil-filler pipe moving or rattling where it should be held still
• Cracks radiating from a mounting hole or from a bend in the bracket
• Fasteners working loose, with fretting marks or bright metal around the holes
• Filler pipe sitting out of position, so the cap fouls or is hard to reach
• Corrosion lifting the paint, with scale between the bracket and its mounting face

🛠️ Service Notes

• Fit the bracket with spacer 820917, as the spacer sets the standoff that keeps the filler at the correct position and angle
• Check filler pipe 20808091 and its seal for cracking where the bracket clamps it, as an unsupported filler works the joint until it leaks
