I have a 2- 6 gallon plastic fuel tanks that I use with a 1976 70 hp Johnson the problem I’m having is the engine will start up a idle but when I give it gas it dies now the vents are open and there happens with both tanks I even open the top of the tanks and still same problem......now I have noticed with the tops on tight and the vents open both fuel tanks will swell up over time when I open the tops pressure comes out ......guess I have bad vents put shouldn’t engine run with the tops off?
