Hi Joe
Ive used a silicon hose. Its flexible enough to stretch over larger barbs i have on the inlet manifold, yet its snug with the MAP sensor barbs on our EC2. It also has significant wall thickness so as not to collapse under high vacuum.
I only ran one line ’t’ off inside the cabin to feed both EC MAP sensors and a Dynon MAP sensor.

Cheers
Steve Izett
