not for American market. average car tanks takes 30-50 dollars of gas. markup on gas prices is really small around 15%. if sold at market prices profit from each delivery will be 4-6 dollars. cost of delivery will be around $20-30 dollars when you count driver salary, truck lease, fuel, etc.
Fuel delivery has been done in US profitably for very long time. its delivery of heating oil to houses but during every delivery they sell a few hundred gallons of oil and thats when the low margins start adding up, $40 delivery won't cut it.
This is not meant for average car tanks. As you can see on their site, this is aimed at trucks and generators with large tanks: https://mypetrolpump.com/
