Thinking about using a VPX in my build. Engine will be UL Power. The ECU (Engine Control Unit) and at least one fuel pump (two on the system) MUST ALWAYS HAVE POWER if the engine is going to work. Would you wire them both separate outside the VPX, or would you wire an Emergency Buss for the ECU and Fuel pump in case of a VPX glitch... EFIS will have a backup battery, so not worried about it. Thanks in advance.
