    I know there could be several places that it can leak fuel but I've only used the thing like 3 times - any suggestions on what to look for - now it has been really cold here lately (down in the low teens) could this have had any affect on what is leaking - it is a Thermo King and its on a 2019 Kenworth T680 - on a side note with the APU not working - is there any way to bypass the engine idle shut down so I dont freeze to death

    Pull the top cover off and look. It should be plumbed into the tank nearest to it, so just follow the lines.
    These new trucks are pretty smart. Depending on the ecm settings you might be able to fool the ambient air temp sensor, but I don’t know where it’s located.

    Try a stick on the throttle pedal just above low idle. Try leaving the tractor parking brake released.
    Tie a piece of wire tied across the coat hangers or something on each side. Hang a one gallon metal bucket in the middle. Put charcoal in it. When it is cooling off trough a few more brickets in the bucket. I was not there but they said a man came home like this. His heater knocked off and he made it home for Christmas. They said he looked like a raccoon. The only thing left white was the rings around his eyes. Not recommended but he but he did not freeze to death.
