      Can a Single 4psi Hobbs Switch Act as a Ground Trigger for 2 Different Pumps?

      Hi all,

      currently working out the kinks on my meth PI and FI stage 3 LPFP. Both are set up to where the pumps are triggered by a 4psi hobbs switch, but I was wondering if its kosher to have the same Hobbs switch act as the ground trigger for both the meth pump and the secondary LPFP? in this case both grounds (from relays, of course) are attached to pin 1 on the hobbs switch, and pin 2 is grounded to chassis.

      OR do I need to grab a second hobbs switch, and use one for each pump? (good thing they stock em at NAPA)

      Thanks!

      IF they're only triggering the relay, then you're fine. The pumps should then have a separate loop to the ground and thicker gauge wire.
