Love that gauge. But the real name of it is RKG.fuelstat.ga.    Don't know where the CPT came from.     Check to see how big that gauge is. Should be 578 or so kbs.  This is actually several gauges in one and if you don't have the right one in there, it will not display all the info.

I found that in this main ga. are round or square fuelstat gauges, some for FS98 and some for CFS2, FS2k2. These also work in FS2k2. Then they are broken down farther into whether it is a prop acft. or a jet.

If you had CFGEdit, then this would be easily fixed. For now I will give you two entries for a prop acft.

This is for a round gauge.

RKG_fuelstat!FuelStatus_recip,  439,138,49

Square gauge.

RKG_fuelstat!FuelStatusSq_recip,  116,279,110,101

Numbers at the end are positioning and size, so insert the ones that your ga. shows in the panel cfg. AND, of course, you will have to add the CPT in front of the gauge name. See if this doesn't get your ga. to display right. Provided you are trying it in a prop acft.

Need anymore help, post here. Tried to find where I got the gauge from. It came with a good set of intructions for panel designers.  Good luck.
