Do you have cfgEdit?
Now that you know I'm not a complete idiot - lets address your VC.
I don't have this panel and I just reformatted my HD and I haven't installed FS04 on it yet, so I'm still a little in the dark.
Some FS04 gauges use a slightly different syntax than FS02 gauges. If the panel is designed for FS02 but you're using it in FS04 you won't see the gauges because of the syntax.
Open your panel.cfg in cfgEdit. Go to the VC panel. Click on "Add Gauge". When the menu pops up go to Spitfire_mk.gau. Add a gauge - it doesn't matter which one or where you add it but put it in a visible portion of the panel, we just want to test the syntax. Make sure the "save old panel.cfg" option is on so you don't lose the existing panel.
You should now see your new gauge. Save and exit.
Go back to panel.cfg and look at the syntax of your new gauge - it should be the last one you added. You should see something like (I'm copying this from your file):
[Vcockpit01]
Background_color=0,0,0
size_mm=256,256
position=7
visible=0
ident=
pixel_size=512,512
texture=$SPIT-LU
gauge12=Spitfire_MKI!Fuel_Warning, 160, 79,26
gauge13=Spitfire_MK1!Fuel_warning, xx,xx,xx,xx
How does gauge13 differ from gauge12? That's your syntax problem.
