If you are using a replacement SU pump, yes.  I think you could flip the
wires and it would work, but the body of the pump would be + while the
body would be - which means a big risk of shorting out.

I think if you have the original SU pump, its not polarity sensitive.  I
don't know hwo to tell if its original or not.

If you have an aftermarket fuel pump with a plastic body you can just
switch the wires.  I think.

That's what I've heard anyway, sprinkled with a little conjecture.
I'm sure someone will correct me if I'm wrong.

Do you really want to have a chance of the radio body shorting out?
What about the antenna?  I believe it grounds as well.

Much safer to just convert to neg ground if you want to use modern
electronics.  It's not that hard.
