That is indeed interesting. Given how much pressure I was running the pumps at, that may have been too much and made them bypass in boost. I backed them off to 60 base pressure now.
As a follow up, I powered up the pumps in tank, and the 255 was spraying fuel out of the plastic top of the pump! Looked fine by visual inspection, but leaked bad when pressured up. So weired, never seen that before. New DW300 is installed and working great!
