Yanmar 2gmf Electric Fuel Pump

Novice question.
I would like to install a Walbro FRB13 (6-8psi, 43gph) fuel pump on my Yanmar 2GMf. I intend to also put a timer in the circuit to circulate the fuel daily for 6-8 hrs to polish and keep the fuel clean when on shore power and run continuously when the engine is running.
Any reason I can't just hook it between the primary filter (racor 120AS or possibly 500 FG) and the mechanical lift pump with a bypass/check valve line and without disconnnecting the mechanical pump? I.e., Is there a problem with head pressure to the mechanical pump and is there an unanticipated consequence if the mechanical pump fails in this circuit?
