To edit a fuel tank, the procedure also starts off with steps similar to those when editing a vessel.
From your Home Port, click the 3-dots at the top right corner of the page. Then click on the Edit pencil icon.
This will open up vessel details. Scroll down to see the section Fuel Tank Setup where the list of fuel tanks is shown.
If you wish to remove a fuel tank, click on the Remove circle icon (with minus sign inside) in line with the fuel tank you wish to remove.
To edit a fuel tank, follow the line of the fuel tank you wish to edit and click on the Edit pencil icon.
This will open up the fuel tank details page. Edit tank details where necessary.
Then click the SAVE CHANGES button to save the changes made.
