App... 97ss 383 D1 intercooled/ Meth 72# Seimens Inj. M6 trans.
My adjustable fuel reg is set for 43psi. The boost ref signal spikes psi to about 52psi. Pump flow output will drop with higher pressure delivery line pressure.
I ran a single Walbro intank 255lph with Ken_Bell BAP volt assist. Still was not enough.
Went to (my custom fab) 2 Walbro 255 lph in tank parallel with single pump #1 on the KB BAP assist. Reworked all fuel delivery line to twin -6an and -8an (helped alot).
I have not experienced any fuel starve problems.
Hope this helps. B.
