When I added a 4 stroke kicker to my Alumacraft, I added a fuel/water separator that had multiple outlets. In doing so, you will always be pulling fuel from a reservoir, thus eliminating any chance of sucking air. Technically, if the T is before the primer bulb on your main line, you can use the T as your joint and the primer bulb for the kicker should not allow any back-flow of fuel all the way to the motor, sucking the line dry.
I have heard of some people putting in a shut-off T-joint that would shut off the kicker line when using the big motor and vice versa.
My reason to go with the fuel/water separator was two-fold. It gave me the second line, and it also filters my fuel so no water goes through the system if some had somehow gotten into the gas tank.
