The first thing I'd be tempted to do is set up a complete system test. Remove the gauges and hook them to a battery and ground the body of the sender, connect the sender wire, and then throw the temp sender in boiling water and see what it reads. Grounding the sender wire should make it either go full scale or to zero, and disconnecting it should make it go full scale one way or the other. Same deal for the pressure sender, but use your air compressor to pressurize a fitting that the sender is screwed into. Disconnect and/or grounding the sender should make it read full scale, one way or the other, so that's an easy test without even removing them from the panel. Maybe you've already tested them that way though. If they were VDO gauges (or Mitchell) the directions should tell you the resistance range for each sender.
