Fuel system talk.

so do i.

ok so base pressure will be say 50psi @ 0 vac, under idle it will be down around 32 or so psi, under boost the fpr will bump it up to about 70 psi at the rail (with 20 psi boost ref).

So I have to put 830 cc injector at 70 psi into a calculator (please link me to the one your using if you can save me a google search to find a good one)to find the lb/hr right?

Then I need to make sure the lb/hr is something the pump can pump. But if there is two pumps, the load will be halved, so what would the flow rating be I would expect?
