1995 vs berlina 5ltr help pleaseeee

[5LTRVS]

hi all i need a bit of help... i have a series 1 vs berlina 5 litre, it has a 60 litre fuel tank, i just bought a 80 litre drop tank / long range tank, it has internal fuel pump, i just wonder whats involved in swapping it over? i been told on the back of the cluster is a switch to select tank capacity is this true? and is there anything else involved or is it a straight swap an just flick this apparent switch over to 80? i have the straps, filler neck hoses pump etc it all came with the tank, any help will be greatly appreciated cheeers.

The switch only changes the trip computer in the way it calculates distance to empty and fuel remaining.

All V8 sedans in the VS range came with a 75 litre tank as standard. You have either wasted your money or someone has replaced it with a 63 litre tank that was standard on V6 models (except for Statesman and Caprice).
