I have another OB question. When i hook the gas hose to the copper line coming from my tank, which is built into the bow, should I leave the primer bulb inline or just go with straight gas line from the copper to the engine with the clip to hook to the engine. If the gas line is always connected is there a need for the primer bulb? Any harm in leaving it in place anyway? Also I was going to put a water separator/ filter inline before the line reaches the motor...will this provide too much resistance to gas flow for the outboard to pull gas thru?
