I have a 1995 150 mercury EFI that I prime at beginning and can run all over the lake with no issues until I sit and fish for an hour or so. I then have to pump the bulb till hard and can run till I sit again for an hour. I have replaced the bulb, anti siphoning valve, fuel lines from the tank to the carb, put in carb kit, and is venting fine. Any good ideas what is going on?
