well pocket i may not have mae myself clear. The old pump that was in there was a holley/ walbro 255 and i used the hose they supplied prob 5ys ago . I knew it was a little effort to drop the tank so i had a new one frome racetronix on stanby and used their hose supplied intheir kit" hopefully submersible".

Low voltage on bank 1 and 2 oxygen sensors and random multiple misfire
Code 300 is never a fun one to trace
One good bit of info is the low side of both O2 sensors are throwing codes so the issue is linked to both banks. That rules out an individual bad injector or bad coil
