I have a Fass 150/150. Used to, when it would rain and I guess a little water would get on the pump or somthin, it ould make ridiculous loud, slurping noises. Well, it has gotten to where it does it all of the time now. It is so loud that I can hear it over my radio sometimes. I am still maintaining good fuel pressure. I would like to get rid of the noise though!!!!
