I make 425 FWHP on CIS with a single 044 up front. When I go EFI, I don't see any reason at all to fit another pump. Because the pressure will drop (roughly halve) - the flow will increase correspondingly.

Are you telling me that the Bosch 044 is the high water mark for inline fuel pumps?
I would think that a high revving NASCAR engine or a 2000 HP drag car would be running a higher flow rate than a 265 lph 044.
If you are fine with the single 044, then why the redundant system with 2 pumps? Is there an issue with pump cavitation and losing pressure under max flow? I am just curious as to the benefits of 2 equal rate pumps performing the same task a 1 higher flow pump.
I am running oil lines forward for my oil tank and I could run fuel lines in a new location if it was beneficial.
Thanks for all the feedback
