a line-boy told me that using the exhaust cold lead to cracking. is this true?
I don't have my tie downs installed for most flights so I use the fuel drain. The reason I use the fuel drain instead of the exhaust is that many ground clamps don't close all the way and won't grip thin metal. The bonus is that you can be sure your fuel tank is grounded when you use the fuel drain.

The ground is to dissipate any static that the aircraft has created during flight. So you want to connect to a location that may have a potential source of fuel to create a situation that you are trying to avoid.........
For the same reason you don't connect the ground jumper to the battery.

Actually, you ground during fueling because the fuel flowing within the pipe or hose can build up a static charge…
One grounds their airplane during refueling to eliminate the difference in charge potential between the airplane and fueling apparatuses. If that difference is great enough, whether due to charge buildup from fuel flowing through the hose or the airplane flying through the air, there can be a spark and therefore a fire.

Technically, both reasons are correct; flying through the air can build up a charge AND pumping gas through a hose will build up a charge. In the end, the point is to reduce the static potential and prevent a spark.
