Re: 1955 johnson 5.5 hp seahorse
i have the same motor and it is in as good condition as it came from factory but i am trying to get answer to gas tank with two lines can i go to one or where can i get a new tank?
im not an expert and have never seen what u are talking about, but if im picturing it right sounds like you have a pressurized gas tank, 1 for pressuring the tank and 1 for gas, their is a linky somewhere on how to add a normal fuel pump, getting rid of the pressurized tank
edit
see if this helps, if not try creating your own tread it will help get your ? answered

also i just read a post someone was asking about the tanks and the guy stated its cheaper to repair the pressurized system, than upgrading. and ill bet if u look hard enough u will be able to find (new/new to u) non rusty tanks, see ebay.......... as a matter of fact, by boat came with one and it wont even work with my motor, the tank is in my back yard, humm need to check it out maybe in good shape
