I think you have the right . . . .
combination with the resistor (100 ohms). If it pegs at 3 bar, then 'button-it-up'!
Personally I've never taken one apart so I don't know what the 'regulator' is; that device that keeps the meter movement pinned above 3 bar.
At this writing I can't see how a resistor can serve as a regulator but can see how a transistor would perform this.
My tech has some older ICs available. Next week I'll check the oil gauge out and let you know what I find.
