Oil pressure problem, maybe?

After cleaning the oil pan and lift valley of sludge, I have her back up and running, when I first started her I had 30 psi on the oil gauge. Then today, I let it run for a while pouring various snake oils (MMO and seafoam) down her throat. I was surprised, she seemed to run smoother with less smoke after burning off the Marvel.
Then I went to shut it off and notice NO oil pressure registering on the gauge. It wasn't making any crazy knocking or sounds, minor lifter sound but I think that would be normal and not louder than before.
I checked the wire on the sender and it seemed ok, so I opened the oil filter canister, took out the filter and cranked it. The inlet for the canister was spurting oil, so I think that would be good, oil is moving.
Can a piece of crude get in the sender hole? Can I test the sender with a multi meter?
I guess I have to get a mechanical tester gauge, anyone buy the one from Harbor Freight ?
And since I got her running for a while, I now discovered a leak in the radiator! Yipppiie!!

Any 0-100 psig gauge will do at this point. It doesn't even have to be that accurate. Just so you know that you have something relative.

But if you are concerned with accuracy though, there is this:
Ashcroft Type 1082 Test Pressure Gauge 0-100 PSI 45-1082-P-S-02L-100# - FLW, Inc.

take the sender out and give a good cleaning with some carb cleaner..... check the oil galley too, see if that helps.
