In this tutorial, I will show you how to respond to a fuel request on ActivateOS.
When a fuel request appears on your actions list, you can select "add fuel". Make sure you have already selected the correct asset that was part of the request. 
If the meter has changed, please update it. If there's an odometer reading, please add that as well.
Next, indicate how much fuel was added. For example, you can indicate "six gallons" here.
To proceed, click on the top amount of fuel added to remove the keyboard. Then, hit send. 
And that's the whole process!
