If a person doesnt have a full 12 volts going to an electronic oil pressure sending unit, will the pressure readings be off a little or a lot? Or does it make any difference if the voltage is a little low?

It most likely makes a difference but it would be impossible to guess how much. Why don't you have full battery voltage going to it?

No problem. Sorry I couldn't help more.

If you are using the factory purple wire from your dash gauge, it will be more like 9v to the sender. The dash instruments have their own voltage regulator.
If you are using an aftermarket electric gauge replace it with a mechanical, failing that power according to gauge manufacturers instructions (probably 12v IGN on).
