I noticed that my 5 gallon plastic gasoline container builds up quite a bit of pressure. Anyone know the limits? Is there any danger of the container rupturing? I noticed my plastic lawn mower gas tank is the opposite and builds up a negative pressure and is indented until I open the cap??

Rupture potential of blowmolded poly is pretty minimal from fuel expansion.
I've had vent caps pop, and had the gasket on the spout leak a few times, but never a rupture.

The pressure limit is exceeded when they burst.  I've had some swell pretty good, seems as when the pressure gets high enough they'll blow the cap off the spout. |

When the county invaded my backyard recently. They took the fireproof cabinet that housed 3 small gasoline containers. Only the good one had a small amount of fuel in it. It had a rigid spout and a pop-off vent. They left me with the oldest one, round and stuck it up next to my house.
