55 gallon drum e85 venting?

[04cobrawhine]

so im thinking of getting a 55 gallon drum of e85 to keep in my garage, like many people. i was wondering if some sort of venting is needed. i know it absorbs moisture so it needs to be keep sealed, however, when in gets hot in the garage, fuel vapors expand, and when it gets cold, they contract (hence the EVAP system on a car). do these vapors have to be vented somehow? im not sure of how much pressure actually builds up because of these vapors, but im sure having a pressurized drum of explosive fuel isnt good. any ideas?

No need to vent, i've had drums of c16 in my garage for years and never had any problems.

I would try to keep it in the most neutral heating cooling spot possible. If you wrap it with insulation it will not expand and contract as much. But, those barrells are built to take this abuse, so no worries?
