When I called Mopar performance direct line they had zero clue what PSI those pumps were. At the time I decided to make my own GM type 2 pump adapter with the assistance of a fellow board member. Recently I swapped out my adapter for the off the shelf unit from Holley, and a Jones Racing pump with aluminum reservoir tank. Cheaper than Bouchillion's reduced PSI unit, no gawdy plastic tank to leak, and readily available GM parts so no Mopar tax.
