You should be able to see the fuel gauge when you display the big telegraph, on the right side. I thought it paired better with the telegraph and detailed speed control of the diesel engines. If you don't it's because of some modification to menu-1024x768.ini.
I took the CE report out because it uses different graphics for the same dials and I find it uninmersive, or perhaps it just satisfies my OCD

. It also saves 0.5mb.
Look at the last picture of the first post.
