I have also ran a manuel Holly with rear fuel cell and 1/2 Alum. (on another car) line to the pump and #8 to a fuel log/splitter to 2 660 center squirters mounted side ways with large bowls. i'm not saying that the pump isn't bad i'm just thinking that you could be draining off the volume with the BP. I wouldn't run a BP on anything except a manuel front mounted injection pump unless it was after the carbs. The tunnel ram with 660's was an 8,000rpm motor ever pass. At one time i had a 5.83 gear with10.5X28.5 Micky's and it ran 127, i had a 9200 chip in it, and it never ran out of gas. You may also have a filter restriction on the flow from the tank to the pump. If i were plumbing it i would have no filter going to the pump, and 1 inline filter #8 to the fuel log after the pump and no return line.

Has worked for me in the past.
