I need to purchase a new fuel line for my 1976 Evinrude 25 HP motor. I have 6 gallon plastic tank and complete hook-up originally used for a 6 HP Fisherman of about the same vintage, but the siphon bulb is shot. My inclination is to reuse the tank and replace the entire line, adding a fuel filter for water. I was in West Marine yesterday, and I noticed that the fuel lines for J/E were in two categories: recommended for EPA-compliant tanks, and not recommended for EPA-compliant tanks (there were also lines described as "universal".) I gather the EPA reg was introduced in 2011 and has to do with sealed.vs vented tanks, but I know nothing else about it. How can I tell if my current tank is EPA-compliant - will there be a statement to that effect on a sticker, or embossed in the plastic? What is the issue that requires two different fuel line set-ups, depending on the tank? Finally, is there any advantage to the boat operator regarding EPA-compliance or lack of same? Thanks for your help!
