Default vacuum for 2 PMags

For those who have duel PMags. Where are you connecting for vacuum?
Thanks, Larry

This is typically T'ed off the MAP pressure line going to your EFIS, which "typically" comes off of the cylinder three.

Be sure to put in some type of restrictor to dampen the pressure pulses.

Aircraft Specialty has a dual PMag setup for the manifold pressure line. It replaces the EFIS line and has appropriately located "T" fittings and lines to the PMags, all custom lengths for the 14. Easy peasy setup.
