yep,the mechanical sender should rea at least 5psi at idle.if it aint got that it is going to "kling" "clang" engine caught.

The big problem is they read backwards and aren't very accurate. But unless you are racing it, you only need to know if you have oil pressure or not. I ran my Duetto like that for years. I have since changed senders and the new one is really inaccurate but it reads. With power on, if you remove the wire from the sender the gauge should go full scale in one direction. Ground the wire to the engine and it should go full scale the other direction. That will confirm that the gauge is working. If you haven't done it already, spin the engine with the sparkplugs out until you have oil pressure. Either use an ohm meter at the sender or connect the gauge wire. Either way, make sure you have oil pressure before you fire it off. The best way to check oil pressure is with a mechanical direct reading gauge with a hose coming from the engine.

My 66 GT indicates the oil pressure pegged to the right with no signal power applied. Can I use a voltmeter to monitor oil pressure on a first-start?
