The tiniest air leak on the suction side will give you starvation problems. Neither a mechanical nor an electric pump will solve it.

Is the line going to the tank new? Does it have any unions or fittings.

Suggest you merely check your mechanical pump with a vacuum gage before bothering to take it apart.
