Ok. No correlation to the knock sensors there. You will have to investigate the harness/sensors. As far as the fuel level, go over your work.........if everything was normal before you touched it.

The knock sensor circuit is pretty simple but,, its in a crappy spot. Do you or have you ever hosed off your engine to wash it???
Heres what the covers for the sensors and the wires look like:
If water gets into the well the sensor will self destruct. The only way to examine the sensors is to remove the intake manifold.
