[QUOTE="AlanT, post: 499810, member: 30185"] I have the old style 6 gallon metal fuel tanks attached to my 2-stroke evinrude. The fuel tanks have caps that are [B][I]NOT [/I][/B]vented. The engine fuel hose is connected via the 2-prong quick disconnect shown below. If I disconnect the hose, the tank will build pressure, so it obviously seals tight - very tight. Everything works fine and the engine gets fuel and has for many years. My question is this......how does this setup vent air [B][I]into the tank [/I][/B]as gas is drawn to prevent a vacuum in the tank and cause fuel starvation? It must be done through the quick disconnect, but how? I have another reason for asking, but I don't want to derail the simple question.........I know how you guys are with shiny objects. LOL [ATTACH type="full" width="546px" alt="1687207163679.png"]115234[/ATTACH] [/QUOTE]
