IPC Fuel capacity

I wanted the digital speedo in my 2012 ford focus mk3, I changed my cluster to a kuga cluser that has the digital speedo, everything works apart from the fuel capacity appearing wrong, I think it still thinks I have a kuga fuel tank, which part of the asbuilt data would I change? Thanks.

Without knowing the part numbers and year of the cluster installed, the only suggestion is to look thru the asbuilt databases for the IPC’s.

I got the model number and year here. If this helps?
