Oil pressure 40 psi at idle/50 psi @2000rpm.

Oil pressure 40 psi at idle/50 psi @2000rpm.
Just got an el cheapo dash guage connected to my '03.
The engine was warm from a run around the block before I connected it to the new sammich' adapter I bought.
The RAVE manual calls for a minium of 10 psi at idle and about 50 when revving(at which point the relief valve opens?).
Is 40psi too high at idle?
For what's worth, the oil pump was replaced about 11,000 miles ago.
Second issue: If I have a on again/off again knocking, diesel like sound that comes from the bottom of the engine, would good oil pressure eliminate bad lower end bearings? It's been there since I bought it 11,000 miles ago. It hasn't gotten any louder and I'm not using oil. The head gaskets were replaced last month and there was no sign of any loose sleeves.

When I really hear it, though, is under load....like going up hill at slower speeds or into my driveway.
The cadence is not even half of the engine rpm as best I can tell.

It could be instrument error in the Auto Zone quality gauge. Alternatively, it could higher because of the postion of the sensing tube.
The take off is from an oil filter adapter that's placed between the oil filter and oil pump.
Aside from a small leak that I'll take care of gasktet maker, it works ok. If it continues to leak I'll just remove it and temporarily reinstall at oil changes just to check the pressure.

It also does it while on the ramps in the garage but I have to be underneath to notice it. I can hear it in the cab when going up the driveway, though.
