You're going to want the unit that goes in the tank. The original pick up for that tank was the bottom of the fuel pump. But you don't want to use that fuel pump because it would be way too much pressure for your carb. So you'll need to get a tube to extend to the lower portion of the tank. But, don't just use any fuel line hose to attach that tube. You'll need a hose rated for today's fuel that can remain submersed. OR, you can use a compression fitting. Otherwise, regular fuel hose will disintegrate. Somewhere after the tank but before the engine, the best option for you will be an electric pump. A low pressure pump. If you can't find a pump with low enough pressure, you'll need a regulator. If I remember correctly, pressure at your carb needs to be no more than 5-7 psi. Most original in tank pumps put out about 45 psi so you can see why you wouldn't want one of those. Oh yeah, at the pick up unit, you'll need to cap the return line as that won't be needed. But you'll only need to cap it on the top / outside of the tank.
Thanks for all the advice but now I am more confused than before. You say I need the unit that goes with the tank but two posts after you say I need a way to fir the 30 ohm unit in there. What do you mean?
Your certain I need an electric pump?
