Rear main seal- replace oil pump?

I'm doing a couple of oil seals this weekend- including the oil pan gasket. While I'm in there would it be a good idea to replace the oil pump? I've had great, consistent oil pressure but I'm just past 150k so I was wondering if now's the time...

X2.

It's a manual pump in there.. So if it works, it works. I would just leave it. You don't want to open up a can of worms.

It would be a really good idea to take the sump down and clean the screen good through.
