the outside is below freezing, the temperature inside the car is 24 ° C. Cospa's strongest FF heater

I made a lot of mistakes, but
The main body, fuel tank, and electric pump can all be installed neatly under the floor.
It was a great satisfaction.
Even if the outside of the car is below freezing, the inside of the car is warm and comfortable.
If you install the FF heater, you can enjoy staying in the car even in winter in Hokkaido.
