Here is inside of old pump. The screw was epoxied closed but i used vicegrips to take it out, unplug harness and pulled right out. You can see the build up in the screen. I thought about cleaning it but i already have the pump and I am tired of working on it. Also the mesh isnt nearly as fine on the new one.
