MSD Pro Billet ignition- are these unusually "voltage sensitive?" Got stranded, looking for ideas

that's annoying about the fuel filter, but i don't think it'd kill the motor unless it hung the needle open and flooded the motor. that would be pretty obvious unless you took your time poking around, then the fuel would've drained into the motor.

everytime my needles have flooded my motor, it ran really rough at idle and would somewhat clean up at part throttle, could use the throttle to keep the motor running...it didn't just die all the sudden with no warning.
