I keep the pump hanging an only put it in the drum when I need fuel. Am I still OK here?
Thoughts?

When you open the drum and release the pressure your in more danger of blowing up than if you just leave it alone.....
Your releasing vapors that can easily ignite from just static.......If it did ignite it would likey ignite the entire container.
These containers expand and contract with the temp. change....
Leave it alone and keep it out of the sun or away from a heat source.
