Once again, our federal government is making changes that will directly affect anglers and boaters, particularly owners of smaller boats and motors. As of January 1, 2011 the EPA requires that all new portable marine fuel tanks follow a zero-emissions policy. To meet these new regulations, fuel tanks can no longer contribute to, or be part of, an "open" fuel system. Prior to this change, fuel tanks released gas vapor into the atmosphere. Now gas vapor is unable to vent and has nowhere to escape, building pressure within your fuel system. This puts your engine at risk of flooding as the pressure could force fuel from your tank to your engine. The Fuel Demand Valve, offered by Attwood Marine, is installed into the fuel hose and keeps fuel from being forced from the tank to the engine as a result of pressure. Instead your engine continues to get fuel on demand, maintaining proper safety and performance. No one wants to deal with the headache of a flooded engine, especially at the boat ramp. Check to see which type of fuel tank you have, and see if you should have the Attwood Fuel Demand Valve. Read more at the Attwood web site here. You heard it here first!
