Hey guys I've taken my 1982 cx500 tank off to clean out rust. I'm going to be using the electrolysis method but I'm having trouble removing the petcock filter. The petcock and tube came out fine however there still appears to be a plastic liner in the tank connection. I assume this is the actual filter which I'd like to clean but I cant figure out how to remove it? It's really jammed in there so I'm soaking it in penetrating oil to see if it will free it up. Does anyone have experience removing these? Also if I cant get it out then does the filter have any components that will get damaged from the electrolysis process?
