The mechanical pump on my Corvair has no trouble sucking fuel up from the wing tanks (in excess of 90 ltr per hour) and in doing so the fuel passes through a Facet 40108 located at the selector. Any restriction to flow is of no consequence. I use the latter only to prime/push fuel in an emergency and have a second pump parallel to the mechanical for redundancy. Viz:
