Blog Post Radium's Ultimate Fuel Pump Test
this is a pretty good explainer on how to pick your pumps
you can see that the brushless pump (BKS1000) provides the most flow. more than enough for anything on this platform
afaik. even at a high boost of 25 psi (assuming your build can even stand that) the BKS1000 needs to output around 80 psi (55 + 25) and will still flow 550lph and only draw 12 amps
