Hey there
The tanks for the 1200 coupe will cost you $450. I will need the pump you are using so that I can fit it to the tank. For everyone else the tank will cost you around that price. Depending on how large we can make the tank. As the sedans tanks are behind the back seat and the spare tyre sits real low in the boot, you may need to cut the tyre well out to make the hole thing worth while. But i havent been under a sedan in a while. Hope this will help
