Those are very low pressure and the pumps are designed to be dead headed. There are no automotive electric fuel pumps designed to be deadheaded, they would quickly overheat and cause vapor lock in gasoline systems (same as running a fuel tank near empty).

The fuel pump is mounted to the side of the injection pump.

I'm thinking I might want to install an electric pump for peace of mind.

No. The fuel pump is extremely simple and reliable. An electric pump does the same function while adding complication and several more potential points of failure.
