It may depend on exactly which model you buy, but I did exactly that with N56ML and N891JF, using the Facet 40108 that is commonly sold by AS&S and Wicks. See http://www.n56ml.com/fuel/ for more on that. The first photo down appears as though there's a "cross" in the system, but they are simply overlapping with a tie-wrap to secure the flex hose end. I get a slight fuel pressure boost on N56ML with both pumps running, but I keep the same pressure regardless on N891JF by using a pressure regulator inline that maintains 3 psi.
