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

The pressure build up in the drum is caused by big swings in temperature . The very last thing you ever want to do is let that pressure out of the drum . First , because of the explosion hazard . Second , because the vapors you're releasing are the light ends and those have a big effect on how well your race fuel performs . Keep any container of race gas in a cool , shaded area that sees as little temperature swing as possible . Inside your shop is good , inside the race trailer is bad . The temps in a closed race trailer are very high and then cool off at night .
You're correct about the pump , only install it in the drum when you need fuel , then take it out and re-seal the container tightly .
