Fuel boost pump
Thanks for all the replies. Actually I am well past the boost pump and all my studies indicate that the Facet pump being a solid state pump does not have a mechanical failure mode like the pumps homebuilders used way back when. I had one of the older non-solid state pumps go south on me and killed the fuel flow. luckily I was right over the field on a test flight following maintenance.
I don't think the old style or the new solid state pumps would or will interrupt fuel flow by a electrical failure. It is the mechanical failure on the older pumps that bit people.
