i'm runnin a 40 2 strk hatsu. i just installed a water/fuel separator recently. i've been running this set up for a few days and had no problems. but the other day i hammered down and the motor just shut down. it was acting like it had no gas. the ball was soft so i pumped it up and it would run for a second. i checked all connections and everything was good. so i bypassed the sep. and it eventually got fuel and didn't have any problems the rest of the day. so has anyone had any problems similar to this?
