1958 18hp sea horse pressurized fuel tank

[Cbausch]

Hello all first post , I bought a boat a bunch of years back and gave away the motor that came with the boat. Later in life the motor found its way back to me . Now I don't think the motor ran for about 15 years but I have faith in it so I brought it home put new plugs in it , gear oil and gas /oil mix , has the original pressurized fuel tank and 2 line connector on it. The fuel lines were dry rotted so I cut back to where it seemed ok to re connect to see if she even starts. Well everything is hooked up and I'm think so I have to pull this cord a million times till the fuel gets to the engine? So here ya go,

1. How do you prime the engine for fuel from the tank?
2. After I know it starts does anyone have a step by step to retro the motor to the single fuel line system ?

Thanks in advance on your responses
