Thanks for letting us know how to fix the problem with the heating. As for the fuel and starting. What I found out was that with an electric fuel pump, the car fired right up right away. With the old manual, one had to crank for ever. On the original pump was a brass hand pump. If one opens the hood and pumps that pump, it seems to help also. My thoughts are that the pump won't hold line pressure and may even siphon back the fuel it can reach from the float bowls. They do make a one way check valve that would solve that particular problem.
