Replacing the filter mesh in the gas tank (or an extraordinary headache) - Toyota Camry, 2.2 L, 1992

I bought a net for myself and Seryoga (BOR), hoping to change it at the same time, but ... The
edges on the tolly pipe fitting were eaten: (
As I understand it, this is a widespread disease. We changed the net for Seryoga, and I started looking for miracle tools.
Last week I climbed with desire there to split everything, but achieve the goal :))
As a result, the fitting was defeated with pliers clamped in a vice.
He took out all the entrails from the gas tank, and the mesh is not original, and even dirty.
Mesh - 70 UAH.
Sekas during disassembly - free :)
