In my old EPI-800 manual from 1987 they state "For INJECTED engines, the fuel pressure is measured at the fuel inlet to the fuel controller assembly" which is well downstream of the engine driven fuel pump. I am using the RSA-5ADI injector (as you probably are) and have taken the fuel pressure from the aft side of the filter housing where there is a fuel pressure connection as shown in their instructions. I have a steady indication of 27 psi with both pumps on and a drop to 25 when the boost pump is switched off.
