I'd replaced the engine about 10,000 miles ago & it worked fine until about 3 months ago. So after driving it that long I've ruled out the oil pump itself. It would've wrecked the engine if it was the oil pump. What is the chance that it's the oil sending unit?

Most likely it is the sending unit, Ford had a batch a few years ago that after some time would show a low reading, I had to replace a bunch for this. It is a simple and cheap part to replace.

Your thinking is good about that sending unit. Sometimes when an Engine is new they put in a break in oil, which is a very light oil. I don't know what section of the country you live in, but weather conditions required different weights of oil. You should be doing well with a 10W30 grade oil. Stay away from synthetics unless you have started your engine with that type of oil.
If the Engine, (and I hate to say this) was not properly broken in, the Connecting Rod Bearings may have been gaulded, which would cause a lower oil pressure over a relatively short period of time.
Reving a new engine beyond recommended RPM will cause the Bearings to flatten a little and lower the oil pressure.
You can try upgrading the weight of the oil to a 10W40 and see if it makes any difference. that will give you a clue.
Keep driving it and keep an eye on that pressure, If it drops too far, you will have to go into the engine again. No good news for this one.

Most oil sending units leak before they go bad, sending oil all over the engine compartment. Was your engine new or rebuilt? Junkyard engine? Oil pressure comes from the bottom end of the engine, not the oil pump. The oil pump can effect pressure but if its pumping then most likely its not the culprit. Have someone check the engine with a manual oil pressure gauge and also run a compression test to see whats really wrong.

Think of the oil pressure guarge in your truck more as an idiot light than a real oil pressure gauge.. Basically all oil pressure gauges of late are just on and off idiot lights.. no real measurement As a real measurement would freak people out at idle (most car makers do that)....
I would say either the switch or the wiring with the switch being a normal concern once oil pressure with a mechanical guage is verified

the excellent ingredient to do is have a mechanic verify the stress with a mechanical gauge so which you would be able to confirm whether it quite is a mechanical challenge or a sending unit, notwithstanding curiously like the bearings must be getting worn. via layout, a definite volume of oil will pass interior the path of the bearings and finally end up lower back interior the oil pan. greater clearance between bearings and engine components ability greater oil can get through ensuing in decrease oil tension. The oil pump is likewise better than possibly worn too, judging via the mileage. The tension would be larger once you first commence driving because of fact the oil is thicker till it heats up. The oil pump turns in relation with engine rpm so whilst the engine rpm is low, including at a provide up easy, the oil pump is popping slower. as quickly as you develop up the engine rpm will enhance turning the oil pump quicker providing you with greater tension. wish this helps!

theres a good chance. Are you seeing any smoke, if so this could be possible. the pump could also be clogged a little. Maybe even the guage. fix it now or you may be replacing your new engine.

you most likely got a problem with the oil pressure sensor. it happened to me with my 95 F150. give it try, but I would run a diagnostics on it first...

test the pressure with a master guage then you will know if its the sender.change the filter as it could be bypassing.

could be the sending unit or gauge. :)
