The fuel pump relay only operates for a few seconds when the ignition switch is turned to "ON". After that the power comes through the oil pressure sending unit.
Are you sure you're not just saying that the ignition initially powers the relay and then the relay is held in by the sending unit.
I would think that the relay itself is always in use and with whatever might be powering it.
Also thinking that the sending unit is in essence a ground return for the relay, as well as it is for the oil pressure gauge.
