Oil alarm comes on...now what?

[kenn]

Without a precision hose gauge designed to measure at psi ranges at about 10psi, a new sender is a more precise measuring tool than an off the shelf gauge.

Weeeellll... I wouldn't be quite that smug about it, and there are other, better analogue gauges with more appropriate ranges available... but I do agree that if a brand-new original-part oil sender isn't indicating a problem, you are probably ok.
