Lets speak about runaway fuel pumps caused by a failed ECUs for a moment. If the fuel pump is a runaway and is constantly pumping fuel and increasing the engine RPMs above its rating... Is the solenoid actually strong enough to hold back all the pressure in the fuel line? Would the fuel line not pop off or even worst have a partial leak emitting fuel mist into the fuse and being ignited by the still running engine. Seems to me.. the best way to cut out the problem would be to have an electronic switch on the fuel pump that is activated by the Tx.. Not the ECU.
