fuel gauge 2007 ford f150

put an extended range fuel tank in a 2007 ford f150. it has a whole 9gal more fuel capacity.

installed the correct fuel pump for that tank as it would have been equipped for 2007.

filled the tank and the fuel gauge reads only to 3/4 tank.

i know with gm tunes, you can adjust the computer so it knows what the sender should read and what the fuel tank capacity is. i dont see that here.

any way of getting that enabled?Attachment 99930

im having the same problem same everything did you ever figure this out. just so happens to be the guy that owned the truck name is wayne. i shit you not.

This is done in IPC (instrument panel cluster) with ForScan for example. Did that multiple times in variety of Fords. Part of as build data.
