Fuel-Tank Vent Bell

Flexible downward-facing bell for the fuel-tank vent line, recreated after rodent damage on a 300CD/T/D application. The creator printed it in flexible filament at 100% infill and describes a friction fit on the black 90-degree elbow. Use fuel-vapour-compatible material, preserve an open vent path, secure the bell against loss and stop if tank venting, odour or leakage changes.
