This sounds stupid, but I presume the filter arrow is pointed towards the carb and not reversed. Run a temporary hose from the fuel tank to the carb laying next to the car. Water in a tank or line will act like air and may not move from where it is at, but it may move to a fitting or restriction and block the passage of fuel. Put a lot of alcohol or dry gas in the tank, this will combine with the fuel so it moves thru the system and passes thru the carb and is burned up. Without something to combine with, a little bit of water will cause a lot of problems. The CARB WAS NEVER THE PROBLEM.
