Building my custom fuel system

I have a 72 suburban with a cummins 12v VE at about 300rwhp.

I need and want an electric fuel pump, and/or a fass I am just not sure which and what.

I am going to pull the engine and replace with a P-pump 24V and I am hoping for 500-550 rwhp when I am done.

Which electric fuel pump do I need? and which FASS do I need. Pressure regulators maybe?

I am want to run my electric fuel pump down stream of the FASS if possible because I am also building a twin tank setup for WVO.

Yes its going to be complicated but I want the best out of all worlds for my 72 Suburban.

Thanks for your help and imput
