Dennis,
I relocated the oil pressure senders to a manifold on top of the engine. And added a vdo oil press sender sender to same manifold for the aux press gauge. So that’s the stock hi, lo, and aux gauge senders on the one manifold.
Manifold is fed via copper pipe from old stock pressure sender location between push rods on left side engine.
Old sender location at rear of engine is now my vdo gauge temp sender.
I’ll admit, honestly, that I don’t know if the temp sender location is a good location, nor if it’s accurately measuring temp.
I have the original oil pump. Had it apart a few years ago and it was within wear tolerances. No gasket on the cover, just sealant. That’s another story, the paper gasket that came with victor reinz kit for that spot was way way to thick. No, I didn’t mistake the inner and outer pump gaskets. I’m not sure of memory but I’m thinking it measured 12 thou.
I take your point about an upgrade to pump.
And I fully agree on oil cooler.
I think my oil pressures are in the same ball park as your fun bus. But I’ve said before, and I’ll say again now :-) , on logging road trips , steep hills , slow driving, hot day, the pressure drops more when the indicated temp gets to about 105C.
Yes, I need a cooler.
I’d be on to that, but work has been crazy over the last few months. And I have no energy when I get home. And weekends... Often a day at work and then there is yard work etc.
Not an excuse, just a reason :-)

GoWesty is measuring and testing the shaft press fit and while a little pricey for the kit I have to say that so far they work well. Fun Bus is still running the original pump at 340K and 190F still holds ~10 psi at idle and >40 on highway. My 91 at 268K with the GoWesty pump holds a solid 20 psi at idle >45 on highway, the relief valve operating. This van also has an oil cooling system.
