Oil pump after being bypassed for a few years

[Odawg753]

Previous owner of my 97 150 bypassed vro system but I have an extra tank laying around in thinking of connecting it again. With that said what are the chances of oil pump still works? Does diaphragm dry out?

No there is no diaphragm on the " oil side "-------It is a wee piston with an o-ring.----I recommend you take the pump apart for inspection.-----Then do the test from factory manual before trusting it.

I know on my older model I couldn't take apart oil side, this year is serviceable?
