IMHO, the best way is to keep them completely separate.
That way you have redundency.
Run a separate discharge line (of the proper diameter) and wire it properly
from the breaker panel.

I have a manual bilge pump in a Newport 27, and
would like to add an automatic electric one.

What is the easiest way to do this? Can I use
(at least some) of the hoses that the mechanical
membrane pump uses?

The membrane pump is mounted in the back of the
cockpit.

Can I put both pumps on the same hose, i.e. can I pull
water through an electric (rule) pump when using the
manual, and can I push water through the membrane
pump with the rule?

If not, what is the next best/simplest setup?

Thanks for help and suggestions,

Chris
