Coban 306A OBD device is not sending fuel data?

Hi guys,
We are having three Coban 306a OBD device. We've plugged the device in three cars. The cars are toyoto corolla, volkwagen passat and isuzu MU7. All cars support OBD2.
Below the OBD and tracker data we are receiving from the car.

imei:xxxxxxxxxxxxxxx,tracker,160302162944,,F,105945.000,A,1302.7479,N,08008.7603,E,7.53,277.59,,1,,,19350,;
imei:xxxxxxxxxxxxxxx,OBD,160302162945,19350,,,1871,8,80.78%,85,81.96%,811,13.89,,,,;

Here see the fuel data is not there. We've chatted with coban support via skype. The OBD is not supporting the fuel, so the OBD is not sending fuel. I dont think all cars is not supporting the fuel. Fuel is our main concern and very important one. we are set the parameter to device as per the document they gave.What is the problem? Could pls help me out of this problem?

Most of the regular cars don't report fuel information via OBD as far as I know, so Coban support might be right in this case.

hey Mah123, did you ever get the coban 306A module to get the fuel data
