I put on a new fuel pump with the glass bowl about a year ago. The glass bowl seems full and I've cleaned it out the other day. I don't have any other fuel filters between the fuel pump and the carbs. I put in a new pickup tube with the screen in the gas tank and all my gas lines are new stainless steel with no kinks. I bought the fuel pump from Chevy Duty. Where did you guys get your fuel pumps? Any brand better than others?
