Oil Pressure Gauge on 2000 GTS

[Carmaker]

Gauge always shows the pressure at about 68-70 PSI. It shows the same at idle or at any higher RPM. I have just noticed this today. Is this just a faulty sending unit or a sign of something else?

id guess sending unit

What size it the wrench needed to get the sending unit out? I don't have anything larger then 3/4 open end wrench.

All those cars in your sig and you have no tools? I would guess larger than 3/4". Probably 1 to 1-1/8". Go buy some tools man!

Thanks for the input. Have plenty of tools but nothing in that size. Was planning on buying the one necessary but not adding much more to that which I already have.
