Let them Rev it to 5000 Grand by which point both power and torque will be rapidly declining and you will have an idea of how your engine is doing. Electric lift pumps seem to work but its down to the Vane pump cavitating and not being able to take the demand of fuel at such high RPMs (in VE terms). First thing i would do though is take the standard lift pump out and see if the gauze needs a quick clean.
