3-8 Total Fuel Remaining
ASCII-coded decimal format (least significant digit is tenths), LSB first

9 Total Fuel Remaining Checksum
Break each decimal value into BCD representation. Using BCD arithmetic, sum the 4
BCD values and convert the lower-order BCD digit to an ASCII coded numeric digit.
Example:
The checksum for a value of 543.2 would be "4" (34H).
