Fuel Tanks on the BF 110

[JG53Frankyboy]

i am using key shortcuts to conrol fuel.
so i have set two keys, every is to toggle throug the fuel'cock' settings of one side.
#1 front, rear, both, none (left engine , or in single engines planes )
#2 front, rear, both, none (right engine)
These are the two left levers.

The right instrument panel, when i use my mousecursor, i get fuelcocknummbers like #3.
I dont think one needs them.

This game is good in simulation some things, but it does not simulate the reality 100% - i dont think it will ever, and i dont think too it cant - never expecting it !
