Air In Fuel Filter?

Evening all,

Not a particulary Packard question but one that can affect any vintage car.

Due to a rusty tank on my Dodge Bros, I have fitted several fuel filters over the past while, between the tank and the carb, before and after the pump, all in different positions and at various heights.

The question is where does air come from in the filter, I have used all types including a type which can be bled.

I have used non-return valves, checked for leaks but all to no avail.

Any ideas?

Pat.
