Finished off the Fuel Filler Neck and installed.
The Fuel Filler Tube is a shortened Holden OE VT Commodore Wagon Filler Tube.
The top half of the tube and its vent tubes are retained but cut just after the breather valve component.
A 45 degree 2" exhaust tube is joined between the filler tube and the tank inlet tube with Mackay rubber fuel 2" hose (Part Number CH5933).
The fuel pipe has been HPC coated for rust prevention.
