You're on the right track. You've got oil. I take it you were still able to drive? No overheating? Just no pressure reading on the gauge I presume? Deffinately go through a process of elimination starting with the cheapest component first. Like I said... you're on the right track. Buying a sending unit is exactly where I'd start.
Plus, (this isn't actually necessary), but I'd recommend finding a place on the block somewhere to tap into and install a quick disconnect fitting for pluging up a mechanical gauge as a secondary under the hood somewhere. Some guys like a mechanical gauge for accuracy and end up routing a small 1/8th inch line to the cab; usually under the column somewhere. But remember... you'd be bringing oil into the cab and thus gives potential for a leak someday, if the threading is not doped or locktighted.
The secondary mechanical gauge is good especially if you get a good name brand that has been qualified through a calibration measure. That way, if you look at your electrical based gauge and you become leary or suspicious of it's truth... you can always pop the hood and check out your permenantly installed secondary mechanical gauge (or snap on the quick disconnect secondary mechanical gauge) and make the comparison between the two before rendering a verdict.
That's how my truck is set up. I'd love to have the mechanical gauge on the interior, but my carpet is too pretty looking to even risk havinging the gauge form a drip sometime throughout its life. Hope this tid bit helps.
