Rally dash redo

Thanks.
I agree. Even cold start up, that's high. If you recall I tested the gages, so I suspect the replacement sender.
I have a new sender from Bill Rolick that is supposedly correct but wasn't able to swap it in yet.

It would be good to test the new sender for pressure vs. resistance. Have come up with a way to do that.
I would get the gray wire off that sender now. Could be overheating that gauge.
edit; Curiosity got me so went to look... 23 ohms on this gauge is 40 psi +/- 5. and you gauge is now showing well over 80 psi which is as far as the scale/chart goes.
