Did just that yesterday. Was pleasantly surprised. 20 psi at idle while hot. Gage on dash rarely got above 20-30 driving down the road.

P.S. Just a heads up. The thread on the pressure switch is not standard pipe thread like your mechanical gauge probable is. It is close enough to gently snug it tight for testing. Will only go in 1 or 2 threads before doing damage. I ran mine for maybe 5 min and it dripped 1 or 2 drips.
