if there is only 8v going to the pump or pumps, i think filter location or quantity is irrelevant. have your battery load tested, and make sure the connections are clean. then start checking voltage input and output at your EEC and Fuel Pump relays. Bad contacts inside of a relay can cause a voltage drop. If you have low input voltage to the relay your going to be looking at a resistance problem in the wiring.
