The fuel pump sending unit has three wires not one.
oil pressure sending unit
As for testing, it is hard to verify that the contacts are not pitted to the point of increasing resistance that causes the voltage drop.
I noticed that my oil pressure gauge had changed slightly indicating higher oil pressure. I changed the sending unit and the gauge started registering closer to where it was.
The fuel pump relay only operates to pressurize the system. It does not operate under normal pump operation. It runs for 2 to 10 seconds when ignition is first turned to "on".
