What is your question?
I changed the battery and the overflow line disconnected from the bottom of battery compartment. How critical is this? I have an overflow line from the battery about 7 " but not connected to anything.

It is a vent tube/hose,vented to the outside of the vehicle. The purpose of the vent hose is to disperse hydrogen gas, which is a byproduct of charging the battery, to the outside. If it accumulates in the trunk it can cause an explosion when you open the trunk (the spark comes from the truck light switch contacts).
