Both the digital and analog oil pressure gauges on my 1998 Corvette are indicating that my oil pressure is at 130 psi. What can be causing this - a defective sending unit. If so, where is the oil pressure sending unit located on this engine?

You know, I forget. I want to say it's under the intake manifold, but I'm not sure. I'll try to look it up, I've got a service manual for it somewhere.

Nah bro, your right on, it is under the intake manifold. Make sure you put a dap of whit out alonf your release bolts because I had a dealership tell me I need a new oil pump and come to fing out none of those bolts were unscrwed. Good luck.

I am experiencing the exact same thing on my 2001. Thank you for this explanation. It is exactly why I entered this forum.
