Oil pressure gauge or sending unit?

I've just gotten a 95 YJ 2.5L and the oil pressure gauge pegs out after start up. At a very slow idle, it reads less than pegged out. Do I need most likely, a new sending unit or a new gauge? Many thanks for your help.

My bet is clean the contacts on the circuit board behind the gauge and it will be fixed. I changed the sending unit on my 91 but mine would register low around 10 highway and 0 at hot idle. Try cleaning the contacts first as its free then if needed get the sending unit ( I paid $20 at autozone for mine)

Most of them do that after start up and then come back to normal after the engine warms up. If yours stays toward max when warm then you need a new sending unit.

Thanks for the replys. I did take out the cluster and cleaned and tightened the contact screws but after installation, it was doing the same thing. I'll pick up a new sending unit and put it in. Many thanks.
