In February 2004, Facet changed the design of their 40171 fuel pump. This pump--used by many builders of Amateur-Built aircraft--was controlled by PPAv's XFR-J fuel pump controller. The changes made by Facet caused the XFR-J to no longer be able to sense the end-of-fuel condition and thus automatically shut off the pump. While other PPAv fuel pump controllers could control other Facet pumps (such as the XFR-K that controls the Facet 40105, 40106, and 40108), PPAv's core XFR business was the XFR-J. To overcome the problem, PPAv developed a new method of controlling the fuel pumps--virtually any brand of fuel pump--by adapting our low fuel sensor to provide an end-of-fuel to the XFR (the XFR-SA). But, since the XFR-SA required external sensing and since the XFR production was labor-intensive, it no longer offered our customers good value for the money. Thus, PPAv discontinued the product line. The full story is here.
