Ha, another retired electrical guy. Like me. You’ll probably be good with 16, but I’d use 14 just to be safe. I had an electric pump (in a very off topic installation) that was a Bosch. Said it would support up to 930hp in a turbo 911. I used #10 for that one.

I’ve got in tank GM pumps on 2 yblocks. One supercharged, one a throttle body EFI. 40# or so. They’re both on #12. So 14 should be safe.
