How will the bulkhead connector hold up to alcohol based fluids like ethanol?

I don't know, but doesn't the alcohol come in a plastic bottle?

Will these work for a 12v 30amp application? i see a qc rating of 500v/ 30a but not sure how this translates to dc.

I would say so, since I am connected and draw about 25A at 12 volts without any heat being developed. Just use a wire rated for more than 30A

How can you solder to the back of the male part you cannot reach it?

Twist the plug shell, then put the shell into the cable and solder the cable, and finally twist it back to install the shell
