Primer Bulb not Refilling w Fuel

I have a Cub Cadet 3075 String Trimmer. The primer bulb wasn't refilling with fuel in a normal manner. So, I replaced the primer bulb and found that the fuel line had corroded into piece in the gas tank. I got the pieces out and replaced the incoming and outgoing fuel lines and the filter stone on the intake.

However, same problem, the primer bulb doesn't refill. What should I fix/replace next.

RE: Primer Bulb not Refilling w Fuel

1. Could you have gotten the lines crossed on the bulb? Do you feel a suction that would suck fuel?
2. Did you check the ports on the bulb for restriction? One side should pull and the other pushes fuel.
3. Did you check your tank�s fuel filter for restriction by removing it off the line?

I just experienced the same problem and the bulb actually showed signs of a vacuum. Plus, it would not fill until I cleaned the filthy screen inside the carb. This is very easy with compressed carb cleaner or "Low" compressed air if there is no varnish (with air pressure pushing the screen "in" vs out or it might come out). If help is needed, I have seen good "YouTubs Etc carb rebuilding" and good text instructions online.
