20 psi oil pressure hot idle

.... Also, red and black and green colors referred to the OEM o-rings. There's no guarantee aftermarket, such as felpro, will be the same color correspondingly. (If you stick with OEM, then you won't be left wondering because the color is different on whatever brand you bought. Comparing old versus new is useless, as you can see above the old ones shrink. Mahle is the OEM, never had a problem using them. )

Here's the instructions on the o-rings. I forgot there's a tapered one., which I've never ran across.

Over the yrs, I have successfully used both of the following o-rings in my 07 6.2L Denali stock pump and pickup tube.
Mahle# B32790 (installed 6/24)
and/or
Felpro# 72401 (installed 12/18)

See the taper? The pic is of the 5+ yr old Felpro still doing its job, but I changed it with the Mahle while I was in there.

I added the 2nd bolt, but didn't use the girdle.
Maybe next time?

Yeah, I used one of these and some oil-resistant thread locker on the two screws for the pickup tube & girdle.
