Betterer! At least I could just swivel it around without driving out the split pin.
So the inspection port gets repurposed as the upper breather hole?
I haven't got the hoses so thats another bit to order.
Can't put tank back in today as forgot to order replacement fuel lines. Bliddy annoyed with myself. The breather valves on the new tank are not broken, so thats one cost saved.
Bentley page 20.34 (not in the contents page annoyingly so I had to look at every page to see if this was documented), pictures the fuel line routes so I now know its the return line which comes in through the sender onto the strainer bucket.
Will spend the day painting the rust out of the engine bay and popping new bits onto the AGG - oil and water pumps, plugs, thermostat cover, timing belt etc.
