3 Gallon Portable Fuel Tank, EPA Compliant, w/o Gauge - Attwood

I purchased this tank for use while fogging my fuel injected Mercruiser per the manufacturer's recommendations. The tank is perfect for that use. However, although no fault of Attwood, the EPA required low emissions design is a joke and can be dangerous if the tank is not properly sealed. I did not have a fuel hose with shut-off connected to the tank when I first placed gasoline in the tank. Although I placed only 2.5 gallons of gas into the tank (on a cool day), fuel started spewing out the fitting about 30 seconds after tightening the fill cap. I quickly loosened the fill cap to relieve what little pressure had built up. My guess is that the few ounces of fuel that spilled out resulted in a lot more gasoline vapor emissions than would ever have been released from an old style tank. Also this could have been disastrous had the fuel leak begun after I placed the tank in the trunk of my car and driven off. I am an environmental engineer and am frequently amazed how idiotic some of the EPA's rules are, particularly those regarding fuel emissions.
