PETERS: It's not necessarily the expansion of the tank material itself, but the air and the fuel too which have a greater impact on tank "puffing" or "imploding". I have a new 60 gallon schoolbus fuel tank mounted on the front of my backhoe trailer. When it is hot out (mid 80's) and nearly empty and it gets very cold overnite (30's) (and lacking a proper vent) it is impossible to pump fuel unless I cock the filler cap open---which takes two hands to open due to internal vacuum. On the other hand going from cold to hot, I have had the filler cap go flying out of my hands being under so much pressure.
