When you thought you'd filled the tank, air is still trapped in the pie dish void and the fuel nozzle cuts out. The pinhole allows controlled venting to occur, so that when the fuel increases in temperature and volume (now that it's out of the ground), it swells into that void and doesn't puke out the vent lines.
THATS WHY YOU DON'T TOP OFF AFTER THE FIRST CLICK.

TOOmuch vent chamber gives the liquid/air time to settle out and is a great feature........but can't cope with massive west-coast changes in temp out of the ground vs. cooking in 95* ambient.

Aftermarket tanks don't have this feature.
Competing claims to the largest volume compared to the competition?

Carl?
I'm sure it may be still early to tell, but we've had a few 80+ degree days, so wondering how the fuel tank system is working out as far as smell/expansion, etc.?
