Hi Gazimoto:

I will ask my friend as to how hot the fuel was when he began fueling. He did say that upon opening the tin, there was a great deal of pressure along with foam that escaped the tin. This continued while he has was filling his fuel bottle and tank.

I think that you may have hit on the only realistic answer that I can deduce. I will call him and ask him about the temperature of his fuel at the time. He has scoffed at me for me keeping my Diesel fuel cool during transit and at the field.

Cheers,

Frank
