Check to see if the engine has a fuel pump. If the fuel line goes directly into the carb, you don't. If it goes into a square shaped thing with two hoses first, you've got a fuel pump.<br />If you have a fuel pump, you only need a one line hose and a regular tank. If you don't have one, you either need to get a duel line and tank (often on ebay, search for 'pressure tank') or covert your outboard to a fuel pump. Normally the former is cheaper if you don't already have a single line and tank.<br />The way it works is this: pressure/vaccum pulses from the crankcase are sent through a check valve, so you only get pressure pulses. This is used to pressurize the gas tank (through one hose) which pushes gas up to the carb (through the other). <br /><br />You may be able to get it running longer by using the primer bulb as a 'fuel pump', pumping gas up to the carb.<br /><br />Get back to us.

Hi, Danny.<br /><br />Welcome to iboats.<br /><br />Your 1959 engine doesn't have a fuel pump. Originally it used a tank with dual lines; one for gas and the other to pressurize the tank from crankcase pressure. Those tanks and lines can still be found on eBay from time to time.<br /><br />To use a modern tank, you would need to adapt a fuel pump to the engine and install compatible hose fittings. www.twincityoutboard.com can probably help you with that.<br /><br />Your correct fuel mix is 24:1; unleaded regular and TC-W3 rated outboard oil. (1 quart oil to 6 gallons gas)<br /><br />The correct spark plugs are Champion J4C, gapped at .030". Set you points at .020 gap.<br /><br />Good luck and let us know how you make out.
