Hi all,

We own a "new to us" boat. My question regards the fuel selector valves w/ twin Crusader 454's. I recently filled up the three tanks, Port, Starboard and Aux. When the port fuel selector switch is in the port position for the port engine and the starboard duel selector switch is in the starboard position for the starboard engine will they both draw from the aux tank? Or, can I only draw from the aux tank in the "Aux position" on both selector valves. We ran for about an hour and a half at 3400rpm and I saw fuel use from both port and starboard tank but nothing from the aux tank, still shows full.

Thanks!
