Sorry for the hijack, but does anyone have a picture of the 'small' tank, my 87 mayfair has one in :S Do i assume from this that the tank was not the original for the car then?
The small 5.5 gallon tank had the securing strap running over the top and my first Mini (a 1975 MK3 Mini 1000) came with this type of fuel tank. Check out the shop pdf pages on Somerford Minis website as you'll find one illustrated there.
I believe the Mini 1275GT got the 7.5 gallon tank first and that could well have been around 1974?
