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 .

Good info
Makes sense
Thanks,
