Great work! What was the small leak? As said above, if your fuel pump was sucking gas out of a temporary supply, and can't draw from the tank then something between the tank and the pump is clogged. The advice to disconnect at the fuel pump and blow air gently back through the line to the tank. You should hear some bubbling if there is gas in the tank. Loosen your gas cap before you do this. Check all the rubber in the fuel supply line from the tank to the pump also. The ethanol in today's gas doesn't play nice with the rubber fuel lines from yesteryear, and you may have a rubber hose somewhere in the line that is collapsed.
