i've already got the y-check valve to prevent back flow on the feed line.

my question is does anyone have any information on a "mallory" switch.

from the limited information i've read, it is boost referenced and will activate the 2nd pump at a predetermined boost level.

This is how i'd like to have it setup, that way i'm not running 2 pumps all the time.

anyone with information or experience??

thanks!

Search for "Hobbes switch" or something of that nature, it's what most FI people use.

Just ground the control side of the relay through the switch and set the boost level.
