Hey thanks for all of your input.
My builder had me drain all of the
oil, check the pan for metal (none found thankfully), de-plumb the Accusump, refill with 7qts and try it. Instant 60psi. I'm baffled how the Accusump, which essentially dangles as a dead end off of the system could affect
oil pressure. My only other thought is too much
oil causing foaming and cavitation. With the Accusump nearly empty due to the low pressure problem, the 7qt pan had nearly 9qts. in it. Any thoughts?
