I have a 2002 sunseeker Moho, with a 55 gal tank, when the tank is full , the pump does not shutoff either doing it manually or set on auto fill, gas comes out underneath , poabably on the filler pipe, will keep pumping until I manually shut off nozzle, probably a quart or more comes out before I can get it shut off, any ideas on this ?
The pump nozzles shutoff when they see back pressure from the gas level reaching the nozzle end. Since you tried several stations I don't think it's a station problem. Therefore the only thing I can think of is there is a vent pipe disconnected or hole in the filler pipe such that the gas level never reaches the end of the pump nozzle because it flows out the hole first. Also if it was just a nozzle problem without proper shutoff the gas would come out the top end of the filler pipe not underneath.
Old school. Listen to the change of pitch as the fuel rises in the pipe. I know this is not the answer you were looking for but, it's all I got.
Your correct on the pitch or sound fuel makes when it's coming up the filler pipe, I heard it just wasn't quick enough, guess I'm just getting old. Lol
My Sunseeker & car does the same thing. What works for me is to insert the nozzle all the way in the pipe, & pull it out about an inch or so. It works for me even on automatic.
