Fuel filler cap replacement

[Chops]

Hi,
Snapped my fuel filler cap at the hinge so I bought one from eBay but unsure how to fit it. Does anyone know..pics or video would be great.
Thanks in advance..

I had a quick look in the Haynes manual but it's not really interested.
The section on removing the fuel tank says you have to remove the wheel and arch liner then the plastic panels in the boot to get at the filler neck fixings.
I'd try the arch liner first as the clips are easier to replace and it probably would benefit from a clean anyway.
The internal panels aren't so forgiving
