What is the year of your car? (It has been a while since I installed my 996 cluster and I have forgotten the colors of my connectors.). If you have the LCD-type cluster I have the EPROM dumps from both the 986 and 996 clusters I used in my 2000. The files are stored on a hard drive and I should be able to find them this weekend.

By a process of elimination you may be able to determine which line of code controls the fuel gauge and update the offending bits.

This post http://http://986forum.com/forums/boxster-general-discussions/43017-carrera-gauge-swap.html shows the code for the old style cluster. Lines 1 through 3 of the code include the odometer reading and the VIN. One of the remaining lines probably has the fuel tank type encoded.
