Since I have decided to use an Ellison TBI I needed to change the fuel pump out for a Facet fuel pump with a higher PSI rating. It appears quite similar visually, but is a higher pressure model. Aircraft Spruce carries this pump, but does not catalog it directly. The number is 05-00813 476459E. The second number set is the Facet number. This pump delivers at least 6.5 PSI.
