oil pressure guage

My 1978's oil pressure gauge  is acting odd. When you turn the key off the needle stops a 40 psi when running it shows about 80. Do you think the problem is the sender, the gauge or a wiring issue?  the engine is a 350 so if it is a sender which one. If it is a gauge can they be found. Thanks, Steve

The gauge on my '78 stays at whatever the reading is when I shut the key off. When I re-start, the gauge indicates the actual pressure.  I don't think that I've ever seen a pressure as high as 80, though.

Whenever I run into oil pressure issues, I check the actual pressure with a mechanical gauge. About any will work that can be adapted to 1/8" pipe for testing. Senders and gauges should be available from Myers or Nostalgic. Probably better, I'll bet someone here knows or has them available once you know what you need.
