1958 Evenrude 35hp fuel line/tank question

[14GR8BOATING]

I just recently purchased a boat with 58 Everude 35hp motor. I figured out that the engine needs the one fuel line going to the motor and one line going back to tank to provide pressure for the fuel. I do not have a older tank, so with the newer plastic tank I have, I just added in the return hose for the air pressure. Engine runs good but tank begins to swell and bulge. I do not want to blow up, so could any one give a suggestion how to work this.<br />Pressure relief vave????<br />Thanks

It works best if you have the correct tank....this isn't ORANGE JUICE your motoring around with. How far can you run when your out on the water and there is a major problem. Use some common sense ...pressure relief valve??? You better get real....I don't mean to slam you but your dealing with GASOLINE out on the water. Go on ebay and purchase the correct tank for 35.00 to 85.00+ depending on their appearance. And have piece of mind that your doing everything you can to be safe.

Or convert it to work with a fuel pump, like a '59+ outboard since you already have the tank & line.

Which avenue would you prefer to pursue? Pressure tanks can be found. A fuel pump can be added. Close to the same total price, but you already invested in a tank and line. The fuel pump idea would cost you the least from this point. More modern models have them and yours can be updated by scavenging parts from a dead younger motor. And they're common as dirt. 28-40Hp Johnsons and Evinrudes of the late 50s to the mid 70s use what you'd need. But if accurate restoration is a goal, the pressure tank would be create a more valuable package. The fuel pump system is safer.
