Governor built into the distrubutor - injector pump.
That's going to confuse a lot of newbies. There is no distributor - just like there is no ignition switch. There is a fuel injection pump assembly (which holds the individual barrels and plungers) and there is a key switch (no ignition system on a diesel engine). It's always nice to eliminate confusion whenever possible. I apologize, but in all my years of wrenchin' & schoolin' I've never heard of a fuel injection pump referred to as a distributor.
I cant keep up with all this.
But FIRST
electric fuel supply (lift pump) first to get your supply. Get it to run smooth consistently at some speed then go from there.
There is some modifications required to install an electric fuel pump, such as cutting into the OEM steel fuel lines, installing a relay, fuse/circuit breaker, oil pressure safety switch, etc.. Not sure the OP wants to get into that right now, just trying to keep it simple.
