Default Priming B20 fuel system

1965 122S sat dry for decades. I replaced the pre-filter and both rubber lines, including on back of fuel tank. I emptied two cans of Brakleen into the tank, sloshed it a little and drained it. Metal line got blasted out with Brakleen and compressed air. Now that I've put 7 gallons in the tank, I crank it over 30 seconds at a time and it can't suck the fuel through the line. Fuel pump appears to be working, through the glass filter dome. Would jacking up the rear of the car help?

Wrap a rag around an air blower so that it will seal to the filler neck. You don't want too good of a seal or you'll balloon the tank. Pressurize the tank just a little allowing excess pressure to escape through the rag. It won't take much pressure to push the fuel up to the pump and carbs.
