Here is a chart of fuel flow curves for bigger injectors (70+ #/hr) and pumps (weldon, aeromotive, fuelab, sx, etc). Injectors are at 25 psi boost only, didn't think it made sense to do it for any less. Pumps are at 13.5 or 14 volts. If you're looking to size pumps/injectors, look for a particlular pump and injector curve to cross above 70 psi. Injector curves are shown for 100% dc, your dc may vary (inj curves will shift to the right for less dc). Thought it might be helpful.
