Hello Zelalem,
Good day. Thank you for your question.
We will require more detailed information on the tanks before we can advise for a solution on how to manage the fuel level. Please contact us via VIP Helpdesk or you can contact your Sales Manager/Distributor on this. If you don't have any contacts with our Sales managers, please contact them on our official website
https://teltonika-gps.com/ and click on the "Contact Us" button. When you will click, please fill the form and submit it.
Note: as a topic, please choose "Vehicle telematics" or you can send an e-mail with the description of your situation to info@teltonika.lt
Thank you for your understanding.
Kind regards.
