OK, Now that everybody has got you convinced that you need an additional pump, lets get this going with what you have installed. Remove the hose to the input side of the fuel pump. When you removed the hose on the input side while installing the replacement pump, air got in the line and the fuel drained backwards all the way down to the tank. That new pump does not like pumping the air out of that long line to get to the gas. It pumps gas well and air very poorly.
I use shop air and a rag. Remove the gas fill and insert the shop air and a rag. Apply air in 1 or 2 second bursts. When the gas starts flowing out of the removed line, have a second person install the line back on the pump and immediately stop the air.
Install the hose clamp and go start your engine. You might have to crank a bit to fill up the line past the pump and the carb bowl. I have done this many times. One time I used a portable air tank instead of shop air on a coach parked out in a field that had not run for many years.
Be careful with shop air. You only need enough to get fuel to flow out of the hose that you disconneted from the fuel pump. You definitely need two people. If one tries this the fuel will run back to the tank before you get up front to reconnect the hose. I have done this with a handheld vacuum pump but it takes a lot of hand pumping to get all of the air out of that very long line.
Once you get it running again you can decide if you want to do one of the suggested electric fuel additions for future use. I have a Carter P4070 on mine but rarely need it. Colonel Ken's suggestion of two P4070s is a good one too.
Good luck....Ken B.
