Just inherited an OLD Johnson Seahorse 10 w/a fuel tank, but no hose

Hi, and thanks beforehand for any and all info. I'll try to provide pics of what the engine looks like. On the the engine there is a pyramid 3-prong 'input', but the tank I have has only 2 inputs (stems). My questions is.. can I use a 2 line pressurized 'squeeze-bulb' between the tank and the engine, and disregard the most 'north' stem? , or do I need three lines? Pics below.....

Again, any and all comments and advice will be greatly appreciated. The engiine has been very WELL preserved, and I belive it'll crank. I just need advice on the FUEL LINES from the engine to the TANK. Thank you to whoever comes thru for me on this.

You have the wrong tank for the motor. It requires a special pressure tank that uses a dual hose system and a special connector for the motor. The engine's crankcase pressure builds in the tank through one of the hoses and forces the gasoline mix out through the other hose to the motor and carburetor.

Merc,
Here is a pretty good article on how to convert your motor to a single line (modern) fuel system and to add the necessary fuel pump to your engine.

If you aren't willing to do this, it might be better off to simply get rid of the motor and get a different single line motor.

Take care

I've got a similiar 1957 Johnson 10hp, which had the fuel pump added to it before my brother acquired it some 40+ years ago. Those 2-line "pressure" tanks are available, but guys want your 1st born for it, plus after 50 years, how much rust is in the tank? Retrofit your gem to a single-line tank, and enjoy the snot out of it.

I retired mine about 10-12 years ago, but there's no doubt that if I put a new impeller in it, it would start on the 1st pull, like it did every time we would take it out of storage for it's once-a-year trip.

Thanks for all the Helpful replies. I read the article about adding a fuel pump and it seems simple enough to do. But since I haven't ever heard this old motor run , I"d like to get a hose that would work with the tank I already have (someone said it's the wrong tank altogether) and TEST it here at home.
Any ideas on how to test this engine with what I have, before retrofitting the 'fuel pump' explained in the article?
THANKS again. Yall's experience is greatly appreciated.

Here is a source for the raw hose for your motor, if you have the tank and motor fittings.

Another source for the double hose:

If you have a double hose tank, and since the hose and connectors are quite expensive in todays market, you could simply use two individual hoses and replace the motor connectors with hose barbs and do a hard clamp on connection to your motor to check for the motors operation.

Then, you could deal with the actual connectors later.
