Okay, they are now pressurized up to 5 PSI see note at bottom...
NOTE: All fuel tanks manufactured after January 1st, 2011 for sale in the United States are required to remain sealed up to a minumum of 5psi per new EPA regulations. This assists in preventing fuel evaporation, saving gas and money. This is normal tank operation. Attwood fuel tanks include an automatic vacuum valve to ensure proper fuel flow and engine operation. All Attwood portable fuel compoments are designed to exceed OEM engine fuel flow requirements.
So the "vacuum valve" is supposed to prevent fuel starvation, and I would assume the cap must still vent anything over 5 PSI on the positive side. I guess that explains your primer bulb issue.
I'm still pretty sure that gasoline under pressure is an explosive risk.....I'm glad the EPA is willing to make that call in light of safety to promote a cleaner environment...Now when will they ACTUALLY restrict smoke stack emissions form all the factories on the great lakes???
